Standard motors are an ignition source in this atmosphere.

Spray Booth Hazardous Area Classification<\/h2>\n<p style=\"margin: 0 0 16px;\">Paint spray booths are classified as hazardous areas under IEC 60079-10-1 and the ATEX Directive because solvent-based paints, lacquers, and primers release flammable vapours during atomisation that mix with air within the booth to form potentially explosive vapour-air mixtures. The extent of the hazardous zone around a spray booth depends on the type of solvent, the spray rate, and the booth ventilation effectiveness.<\/p>\n<div style=\"display: grid; grid-template-columns: repeat(auto-fill,minmax(240px,1fr)); gap: 14px; margin: 0 0 20px;\">\n<div style=\"background: #fff; border: 1px solid #d0dff0; border-top: 3px solid #dc2626; border-radius: 8px; padding: 14px 16px;\">\n<div style=\"font-size: 14px; font-weight: bold; color: #dc2626; margin: 0 0 6px;\">Zone 1 \u2014 Inside the Spray Booth<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">During active spray operations, the interior of the spray booth is Zone 1: an explosive solvent vapour-air mixture is likely to be present during normal spraying. The spray zone extends from the floor to the ceiling and the full width and depth of the booth interior. All electrical equipment within the booth boundary \u2014 including the exhaust fan motor, any conveyor drive inside the booth, and any lighting \u2014 must be ATEX\/IECEx certified for Zone 1 service.<\/p>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d0dff0; border-top: 3px solid #d97706; border-radius: 8px; padding: 14px 16px;\">\n<div style=\"font-size: 14px; font-weight: bold; color: #d97706; margin: 0 0 6px;\">Zone 2 \u2014 Adjacent Areas<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">The area immediately outside the spray booth opening (within 1 m of the booth face opening), the area around any spray booth ventilation supply or exhaust duct openings (within 1 m), and the area around paint mixing rooms (within 1 m of any open container) are classified as Zone 2. Motors in Zone 2 must be certified Ex d or equivalent for Zone 2 service. A Zone 1 certified YB2 motor is also suitable for Zone 2 installation.<\/p>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d0dff0; border-top: 3px solid #1e6fa8; border-radius: 8px; padding: 14px 16px;\">\n<div style=\"font-size: 14px; font-weight: bold; color: #0a2240; margin: 0 0 6px;\">Non-Classified Exhaust Fan Position<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">If the exhaust fan is located on the roof of the building or in an external plenum more than 3 m from the spray booth exhaust duct opening, it may fall outside the classified zone boundary. However, the exhaust airstream itself may contain solvent vapour above the lower explosive limit (LEL) if the booth ventilation rate is insufficient, making the fan impeller and motor a potential ignition source. Korea Ever-Power recommends always specifying YB2 Ex d for both exhaust and supply fan motors on spray booth ventilation systems regardless of fan location relative to zone boundaries.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- SECTION 2 --><\/p>\n<div id=\"solvent-group\" style=\"margin: 0 0 48px;\">\n<h2 style=\"font-size: 26px; font-weight: 800; color: #0a2240; margin: 0 0 16px; padding-bottom: 10px; border-bottom: 2px solid #d0dff0;\">2.

Exhaust Fan Motor Specification for Spray Booths<\/h2>\n<p style=\"margin: 0 0 16px;\">The exhaust fan is the critical safety-critical motor in a spray booth installation. Its primary function is to maintain a minimum air change rate through the booth (typically 0.5 to 1.0 m\/s face velocity) to dilute solvent vapour below 25% of the LEL at all times during spray operations. If the exhaust fan motor fails and the fan stops during spraying, solvent vapour rapidly accumulates in the booth to potentially explosive concentrations \u2014 making the exhaust fan motor reliability and explosion-proof specification paramount.<\/p>\n<div style=\"display: grid; grid-template-columns: repeat(auto-fill,minmax(260px,1fr)); gap: 14px; margin: 0 0 20px;\">\n<div style=\"background: #f4f7ff; border-radius: 8px; padding: 14px 16px; border-left: 4px solid #1e6fa8;\">\n<div style=\"font-size: 13px; font-weight: bold; color: #0a2240; margin: 0 0 5px;\">Fan Power and Motor Sizing<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">Spray booth exhaust fan power depends on the booth face area, face velocity, duct static pressure loss, and fan efficiency. For a typical automotive spray booth 4 m wide \u00d7 2.5 m high at 0.5 m\/s face velocity: Q = 4.0 \u00d7 2.5 \u00d7 0.5 = 5.0 m\u00b3\/s. At 200 Pa duct static pressure and 65% fan efficiency: motor power = 5.0 \u00d7 200 \u00f7 (1,000 \u00d7 0.65) = 1.54 kW. With service factor 1.25: select YB2 2.2 kW, 4-pole or 2-pole, Ex d IIB T4.<\/p>\n<\/div>\n<div style=\"background: #f4f7ff; border-radius: 8px; padding: 14px 16px; border-left: 4px solid #1e6fa8;\">\n<div style=\"font-size: 13px; font-weight: bold; color: #0a2240; margin: 0 0 5px;\">Motor Position: Inside or Outside Zone 1?<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">The fan motor may be belt-driven from outside the Zone 1 boundary through a shaft penetration in the booth wall, with only the impeller inside the booth. In this case, the motor shaft seal and the motor itself may be in Zone 2 rather than Zone 1. However, Korea Ever-Power recommends YB2 Ex d IIB T4 for both Zone 1 and Zone 2 positions on spray booth fans \u2014 the motor is directly connected to the fan impeller that handles explosive atmosphere, and any motor fault that generates heat must be contained within the Zone 1\/2 motor specification. Do not use standard motors even if the motor body is claimed to be outside the classified zone.<\/p>\n<\/div>\n<div style=\"background: #f4f7ff; border-radius: 8px; padding: 14px 16px; border-left: 4px solid #5bb3f0;\">\n<div style=\"font-size: 13px; font-weight: bold; color: #0a2240; margin: 0 0 5px;\">Interlock: Spray Gun Inhibit Without Fan<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">Every spray booth must have an airflow interlock that inhibits spray gun operation if the exhaust fan motor is not running or if the measured face velocity falls below the minimum safe level. This interlock is typically achieved with an airflow switch or differential pressure sensor in the exhaust duct, connected through a safety relay to the spray gun supply circuit. The YB2 exhaust fan motor must start and prove airflow before the spray interlock permits the spray gun to operate.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- SECTION 4 --><\/p>\n<div id=\"conveyor-motor\" style=\"margin: 0 0 48px;\">\n<h2 style=\"font-size: 26px; font-weight: 800; color: #0a2240; margin: 0 0 16px; padding-bottom: 10px; border-bottom: 2px solid #d0dff0;\">4. Booth Conveyor Motor Requirements<\/h2>\n<p style=\"margin: 0 0 16px;\">Continuous coating lines pass work pieces through the spray booth on overhead conveyors or floor-level chain conveyors. Any conveyor motor or gearbox installed within the Zone 1 boundary of the spray booth must be certified to the same Ex d IIB T4 specification as the fan motor. There are no exceptions for conveyor motors based on their small size or low power rating \u2014 a 0.55 kW conveyor drive motor inside a spray booth is as capable of igniting a solvent-air mixture as a 22 kW fan motor.<\/p>\n<div style=\"display: grid; grid-template-columns: 1fr 1fr; gap: 16px; margin: 0 0 20px;\">\n<div style=\"background: #fff; border: 1px solid #d0dff0; border-top: 3px solid #1e6fa8; border-radius: 8px; padding: 14px 16px;\">\n<div style=\"font-size: 14px; font-weight: bold; color: #0a2240; margin: 0 0 6px;\">Overhead Conveyor in Spray Zone<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">Overhead chain conveyors passing through spray booths use drive motors located outside the spray zone where possible, with the conveyor chain entering and exiting the booth through small openings. When the conveyor drive motor must be located inside the spray zone (for compact booth layouts), specify YB2 0.55 to 3.0 kW Ex d IIB T4 for the drive head. The motor must also be rated for continuous S1 duty at the conveyor line speed without overloading, as any motor overload in an explosive atmosphere creates a T4 surface temperature exceedance risk.<\/p>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d0dff0; border-top: 3px solid #5bb3f0; border-radius: 8px; padding: 14px 16px;\">\n<div style=\"font-size: 14px; font-weight: bold; color: #0a2240; margin: 0 0 6px;\">Floor Conveyor in Spray Zone<\/div>\n<p style=\"font-size: 13px; color: #444; margin: 0; line-height: 1.65;\">Floor-level slat conveyors or roller conveyors carrying work pieces through a horizontal spray booth have motors in the spray zone floor area. Solvents are heavier than air and tend to accumulate at floor level \u2014 the floor area inside a spray booth may have higher solvent concentrations than the mid-zone where the spray plume is. All floor-level conveyor motors inside the booth must be YB2 Ex d IIB T4.

Most water-based paint formulations still contain a percentage of co-solvents (typically 5 to 25% by weight) such as glycol ethers, isopropyl alcohol, or ethanol to control flow, levelling, and film formation. These co-solvents evaporate during spraying and may create flammable vapour concentrations under certain conditions \u2014 particularly in a booth with inadequate ventilation or if the co-solvent content is high. Review the safety data sheet for each product used; check the flash point and vapour pressure of the co-solvent content. If the paint flash point is below 55\u00b0C (the threshold for Zone classification under IEC 60079-10-1), the spray booth should still be classified as a hazardous area and Ex d motors remain mandatory. Contact your local hazardous area classification authority for guidance on the specific classification of water-based paint booths in your jurisdiction.<\/p>\n<\/div>\n<\/div>\n<div style=\"border: 1px solid #d0dff0; border-radius: 8px; overflow: hidden;\">\n<div style=\"background: #0a2240; padding: 13px 18px;\">\n<div style=\"font-weight: bold; color: #fff; font-size: 14px;\">Can I use a VFD to control the spray booth exhaust fan speed for energy saving?<\/div>\n<\/div>\n<div style=\"padding: 16px 20px; background: #fff;\">\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.75;\">Yes \u2014 variable speed control of spray booth exhaust fans is an effective energy-saving measure because the fan only needs to run at full speed during active spraying. During idle periods between spray cycles, the fan can run at reduced speed (maintaining a minimum purge airflow to keep solvent vapour below 10% LEL) at significantly lower power. However, the VFD itself must not be installed within the Zone 1 or Zone 2 boundary \u2014 it must be located in a safe area control room or in a certified Ex p (pressurised enclosure) cabinet within the classified zone. The motor connecting the VFD to the fan must be the YB2 Ex d IIB T4 regardless of VFD speed. For VFD spray booth exhaust fan systems, Korea Ever-Power recommends also specifying the YB2 with IC416 forced cooling (separate blower motor) rather than relying on the standard IC411 shaft-mounted fan, as the IC416 maintains full motor cooling at reduced fan speed. This prevents the motor surface temperature from rising above the T4 limit when the fan runs at reduced speed in the Zone 1 environment.<\/p>\n<\/div>\n<\/div>\n<div style=\"border: 1px solid #d0dff0; border-radius: 8px; overflow: hidden;\">\n<div style=\"background: #0a2240; padding: 13px 18px;\">\n<div style=\"font-weight: bold; color: #fff; font-size: 14px;\">How often must the YB2 exhaust fan motor be inspected in a spray booth installation?<\/div>\n<\/div>\n<div style=\"padding: 16px 20px; background: #fff;\">\n<p style=\"font-size: 15px; color: #374151; margin: 0; line-height: 1.75;\">IEC 60079-17 (Inspection and maintenance of electrical installations in explosive atmospheres) requires that hazardous area electrical equipment including YB2 motors be subject to periodic inspection. For Zone 1 installations (inside the spray booth), close inspection is required at minimum every 3 years \u2014 though in practice, paint spray booth motors should be inspected annually due to the aggressive overspray environment. Each inspection must verify: all fasteners present and at correct torque; terminal box lid correctly fitted and sealed; cable glands tight and Ex d certified; external paint build-up removed (which can insulate the motor and raise its surface temperature above T4); motor frame not corroded; and motor bearing condition checked by vibration measurement or operating temperature. Records of each inspection must be kept as part of the facility explosion protection document under ATEX Article 7.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- CTA --><\/p>\n<div style=\"position: relative; background: linear-gradient(135deg,#071828 0%,#0a2240 50%,#0e2e58 100%); border-radius: 12px; padding: 44px 40px; text-align: center; margin: 0 0 20px; overflow: hidden;\">\n<div style=\"position: absolute; top: 0; left: 0; right: 0; height: 3px; background: linear-gradient(90deg,#1e6fa8,#5bb3f0,#1e6fa8);\"><\/div>\n<p>&nbsp;<\/p>\n<div style=\"position: relative; z-index: 1;\">\n<div style=\"font-size: 11px; font-weight: bold; letter-spacing: 3px; text-transform: uppercase; color: #5bb3f0; margin: 0 0 12px;\">Korea Ever-Power \u00b7 YB2 Series \u00b7 ATEX Spray Booth Fan and Conveyor Motors<\/div>\n<h2 style=\"font-size: clamp(18px,3vw,26px); font-weight: 900; color: #fff; margin: 0 0 12px;\">Need Certified Explosion-Proof Motors for Your Spray Booth?<\/h2>\n<p style=\"color: #b0d4f0; margin: 0 0 24px; font-size: 15px; max-width: 520px; margin-left: auto; margin-right: auto; line-height: 1.65;\">Korea Ever-Power YB2: ATEX + IECEx Ex d IIB T4, IP55, 0.55\u2013200 kW.
