Biotechnology labs demanding stable airflow and low noise.
FAQ :
1,Q: How does the 2500 CMH airflow handle heavy metal dust in
welding shops?
A: The cyclonic pre-filtration system traps 95% of sparks and
coarse particles (>50μm), while the H14 HEPA filter captures
99.995% of fine metal fumes (0.3μm). Combined with 1.2m/s face
velocity, it achieves 12 ACH (air changes per hour) in 500m³
spaces—critical for OSHA compliance in welding zones.
2,Q: Why is ATEX certification vital for chemical plant FFUs?
A: Our ATEX Zone 1/21 rating ensures:
Spark-free operation: Brushless EC motor eliminates ignition risks
in volatile VOC atmospheres.
Static dissipation: Grounded steel housing prevents charge
accumulation (<0.1μJ).
Gas-tight seals: IP65 rating blocks corrosive chemical vapors from
damaging internal components.
3,Q: Can this FFU withstand foundry-level heat and debris?
A: Yes, the high-temp steel alloy frame operates continuously at
80°C (176°F), with:
Ceramic-coated filters resisting thermal degradation.
Debris deflector grid blocking falling particulates >5mm.
Automated purge cycle clearing accumulated dust during shutdowns.
