High-Volume Steel FFU | Industrial-Grade Air Filtration for Harsh Environments | Explosion-Proof HEPA System & Heavy-Duty Construction

The High-Volume Steel FFU 1175X575X277 revolutionizes air purification for extreme industrial environments, including metal processing plants, chemical facilities, and foundries. Engineered with 3mm reinforced steel housing and an ATEX-certified explosion-proof motor, this FFU delivers 2500 CMH airflow while maintaining 99.995% H14 HEPA efficiency in high-dust, high-temperature conditions. Its corrosion-resistant nano-coating and IP65-rated seals ensure reliable operation in corrosive or explosive atmospheres, meeting OSHA and ISO 14644-1 Class 4 standards.

Key Features

1. Robust Construction: Aluminum-zinc plate ensures superior durability and corrosion resistance.

2. High-Performance Motor: MRJH motor with metal iron impeller delivers stable, three-gear adjustable airflow (0.45–0.95 m/s ±5%).

3. Advanced H13 Filtration: Non-partitioned HEPA filter (1170×570×69 mm) achieves 99.995% efficiency at 0.3μm particles.

4. Energy Efficiency: Narrow power range (150–190W) balances performance and operational costs.

5. Low-Noise Operation: Engineered for 48–58 dB (tested 1.5m below filter), minimizing disruption in labs or production areas.

6. Vibration Control: ≤5μm peak vibration ensures compatibility with precision instruments.

Application Scenarios

Pharmaceutical cleanrooms requiring ISO 100-class (H13) filtration.

Semiconductor manufacturing with strict particulate control.

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.
