Explosion-proof FFU
Fan filter units in an explosion-proof construction for cleanrooms where flammable solvents, vapours or dusts are handled, bought by pharmaceutical, electronics and food plants that must keep air filtration running in a classified hazardous area.
Description
An explosion-proof FFU is a fan filter unit built so that air filtration keeps running safely and reliably in flammable or explosive environments. The unit draws air through a HEPA filter and discharges cleaned air into the room. The design focuses on safe operation in hazardous areas, with low noise and reduced energy use; the source data states energy savings of at least 48% at initial filter resistance. Speed is adjustable in stages or steplessly, which helps cut running cost. The intended use spans cleanrooms in pharmaceutical, electronics and food production.
Features
- Explosion-proof construction for continuous running in flammable or explosive atmospheres.
- HEPA-stage filtration of supply air.
- Multi-stage or stepless speed control; the source data states energy savings of at least 48% at initial filter resistance.
- Low-noise running.
Applications
- Pharmaceutical cleanrooms where solvent vapours are present
- Electronics production areas with flammable materials or dusts
- Food and beverage areas with combustible dusts or vapours
Supply scope
What is supplied, and what stays with the buyer.
- Fixed configurations only: module size, supply voltage, filter grade, speed control and the required explosion-protection rating are confirmed before quotation.
- Each quoted configuration comes with its specification sheet and packing data per unit.
- Replacement filters and spare fans are quoted with the units so first-line maintenance can be planned.
- Installation into the ceiling grid, electrical connection, hazardous-area wiring and airflow balancing stay with the buyer or the buyer's contractor.
