Universal Explosion-Proof Hoods

Terra’s filter fan unit motors are rated for 5 years of continuous, 24/7 operation, if the HEPA filters are consistently replaced. To accurately monitor your HEPA filter’s saturation levels, purchase Terra’s audible and visual filter replacement alarm system.

UL-listed, NEC Class I, Division 1 Explosion Proof fan/filter unit provides HEPA filtration where solvent vapors, dust and other flammable hazards are present; all conduit and switches also meet explosion-proof requirements.

UL-listed for Class I, Division 1 and 2, Groups C and D areas, this low profile LED light produces 3,600 lumens and operates from 120 to 277VAC, 50/60Hz. The heat-dissipating housing increases the efficiency and lifespan of the LEDs.

UL-rated explosion-proof switches are connected to the lights and blowers using specialized conduit with potted fittings. All electrical components are sealed to eliminate potential ignition points.

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.
