Flameproof Bug Blower Fan — Manufacturer & Supplier, India
Vayuvents manufactures Flameproof Bug Blower Fans with IS 5572 / ATEX Ex-d certified motors and non-sparking impellers for Zone 1 & Zone 2 paint booths, chemical plants, and hazardous areas. Mumbai. Call +91 90961 88703.
A Flameproof Bug Blower Fan is a directed air blower with an IS 5572 / ATEX Group II certified flameproof (Ex-d) motor and non-sparking impeller — designed for safe operation in Zone 1 and Zone 2 hazardous classified areas where a flammable or explosive atmosphere may exist.
The most common application is the pre-paint surface blowdown inside automotive paint spray booths — a Zone 1 area during spraying operations. Removing dust, insects, and lint from the vehicle surface immediately before paint application is critical for defect-free paint finish, but any electrical equipment operating inside the spray booth must be certified for Zone 1 hazardous area service under IS/IEC 60079.
Vayuvents flameproof bug blower fans use IS 5572 certified Ex-d flameproof motors, non-sparking aluminium alloy impellers (for IIA/IIB gas groups) or anti-static GRP impellers (for IIC hydrogen service), and earthed MS casings — eliminating both electrical ignition and mechanical spark risks in the solvent-vapour atmosphere.
Full hazardous area documentation including Ex certificate reference, gas group, and conformance to IS 5572-2009 / IEC 60079 supplied with every unit for your PESO installation permit and factory inspection requirements.
Key Features & Benefits
IS 5572 Ex-d Flameproof Motor
Certified flameproof enclosure contains internal ignition — prevents flame propagation to Zone 1 & 2 solvent vapour and flammable gas atmospheres.
Non-Sparking Impeller
Aluminium alloy (IIA/IIB) or anti-static GRP (IIC) impeller — eliminates mechanical ignition risk from impeller contact or electrostatic discharge in explosive atmospheres.
Earthed Casing
All metallic parts permanently earthed — prevents electrostatic charge accumulation and electrostatic discharge (ESD) ignition risk in solvent vapour environments.
Directed Pre-Paint Jet
High-velocity directed airjet removes dust, lint, and insects from vehicle or component surfaces inside paint booths — critical for defect-free automotive paint finish.
Paint Booth Certified
Specifically designed and documented for automotive OEM and refinishing paint spray booth Zone 1 service — the most common flameproof bug blower application.
IP55 Weatherproof
IP55 motor enclosure handles the humidity, overspray mist, and water wash-down of paint booth environments without motor damage.
Full PESO Documentation
IS 5572 certificate, gas group classification, Ex certificate reference, and IS 3588/IS 4894 performance certificate supplied for PESO installation permit.
Zone 1 & Zone 2 Rated
Certified for both Zone 1 (flammable atmosphere likely during normal operation) and Zone 2 (occasionally present) — covers the full range of paint booth and chemical plant hazardous classifications.

A bug blower is a motor-driven fan unit that produces a sustained high-velocity directed airstream at 20 to 40 m/s through a nozzle. Unlike a compressed air gun that draws from a finite compressed air reservoir and depletes it quickly, a bug blower produces continuous airflow for as long as it runs — making it far more economical for cleaning large surfaces such as vehicle bodies, ship decks, and factory equipment. It also produces cleaner, oil-free air compared to most compressed air systems.
Bug blowers are effective for removing: loose insects and bug splatter from vehicle, aircraft, and ship surfaces before washing; salt deposits and dust from electrical louvres and panel faces; lint and fluff from textile machinery; grain chaff and insect infestations from grain handling equipment; solder balls and flux residue from PCB assemblies; dust from transformer cooling fins and electrical panel internals; and pre-paint dust and debris from industrial component surfaces.
Yes, with appropriate construction selection. Standard MS bug blowers are used in general food factory areas. For high-care zones (open product areas, ready-to-eat manufacturing), Vayuvents supplies bug blowers in SS304 construction with food-safe paint and oil-free sealed bearings — meeting FSSAI hygiene requirements for food processing equipment. The air-only blowdown method is preferred in food areas because it avoids water or chemical contact with product or machinery.
A marine bug blower has an anti-corrosion epoxy primer plus polyurethane topcoat paint system rated for salt spray, stainless steel hardware throughout (no carbon steel fasteners), and an IP55 or IP56 motor enclosure for the high-humidity salt-laden coastal and shipboard environment. Standard MS bug blowers would corrode rapidly in marine service. Vayuvents supplies marine-grade bug blowers as standard for all coastal, shipyard, and vessel supply.
Yes. Paint spray booths are classified Zone 1 hazardous areas under IS/IEC 60079 due to the flammable solvent vapour atmosphere during spraying. Any electrical equipment operating inside the spray booth — including bug blowers used for pre-paint surface blowdown inside the booth — must have IS 5572 / ATEX certified flameproof Ex-d motors and non-sparking impellers. Vayuvents supplies flameproof bug blower fans specifically for paint booth service.
Standard Vayuvents bug blowers are supplied in 415V 3-phase 50Hz for workshop and factory fixed installation. For portable service and locations where 3-phase is not available, 230V single-phase versions are supplied for smaller fan sizes. Battery-powered portable variants are available on request for use in locations without fixed power supply — aircraft apron, ship dry dock, and outdoor construction site applications.
