Exhausters fans for confined spaces (CATEC device)

Air exhausters fans - also called COBRA fans - are essential equipment for working in confined spaces - totally or partially closed areas - with specific risks of asphyxiation, intoxication, fire, and explosion. The CATEC® system (Certificate of Competence to Work in Confined Spaces) defines the recommendations and good practices for risk prevention in confined spaces. The air exhausters fans are one of the means to be used to intervene in complete safety.

Air exhausters for confined spaces
  1. Compact and lightweight, the UB20 air exhaust fan - also called COBRA fan - is the reference for confined space ventilation systems in the water and wastewater sector. Reversible, it brings up to 1,392 m3/h of fresh and healthy air in the duct in poorly ventilated, oxygen-poor, or potentially toxic areas.

    • Industrial air exhaust fan for intervention in confined spaces in compliance with the CATEC device
    • Numerous accessories are available: charger + battery pack, ducts, connection sets, turbo-torque, heating system, etc.
    • Double-walled body made of high-density, impact-resistant polypropylene
    • Plastic carrying handle for easy handling
    • Quiet operation of 74 dB
  2. The EFI150 large airflow exhaust fan's mission is to exhaust or inject large volumes of fresh, healthy air into confined or large-volume spaces such as tunnels, basements, or canopies. It is constructed with durable housing to withstand industrial workspace environments and delivers an airflow of 7 580m3/hr (without ductwork).

    • Large airflow exhaust fan for tunnels and large volume confined space applications (CATEC device)
    • Antistatic ABS housing reinforced with glass fiber resistant to corrosion and chemical products
    • 7 580 m3/h flow rate without duct, 5 404 m3/h with 4.6 m duct + 90° elbow
    • Duct outlet diameter 16″/400 mm - Delivered with 4.6m power cord
    • Motor 1.1 kW, single-phase power supply 115V/230V 50/60 Hz
  3. The UB20xx is an ATEX exhaust fan (COBRA ATEX fan) designed for use in potentially hazardous environments with a risk of explosion. It is particularly suitable for operations in chemical and petrochemical industries, mills and silos, biogas plants, public dumpsites, and water purification and treatment plants.

    • ATEX high-pressure exhaust fan for ventilation or extraction of air in explosive atmospheres
    • Safe switch in explosion-proof housing to avoid risks during ignition
    • IP55 antistatic ABS housing with glass fiber reinforcement and carbon lining
    • Weatherproof, shockproof, fireproof, and chemical resistant
    • 1 392 m3/h flow rate in the open air, 1 025 m3/h with 7.6 m duct + one right angle
  4. The EFI150xx ATEX large airflow fan intends to provide dust, fume, exhaust, or clean air ventilation in explosive environments in the industrial, marine, and aviation sectors. Its antistatic polycarbonate/ABS housing makes it resistant to corrosion, chemicals, and shocks and delivers an airflow of 7 580 m3/h (excluding duct).

    • ATEX high flow exhaust fan designed to operate in IIB T6 Gb type II 2 G EX areas
    • Fiberglass reinforced antistatic housing resistant to impact, corrosion, and chemicals
    • 7 580 m3/h flow rate without duct, 5 404 m3/h with 4.6 m duct + 90° elbow
    • 16'' (400 mm) 21-blade aluminum impeller mounted directly on the motor
    • 1.1 kW motor, single-phase power supply 115/230V 50/60 Hz

The air exhausters fans are reversible devices with two distinct functions:

Ventilation: this function is to dilute toxic gases and vapors, and provide clean and healthy air all along with the intervention of the people in charge. For efficient ventilation, foresee a fresh air flow referring to 20 times the volume of the space per hour. Thus, for a 30 m3 area, the fan flow rate should be at least 30 x 20, i.e. 600 m3/h.

Extraction: this function is to evacuate dust, smoke, and toxic gases from the confined space. However, be careful to choose an ATEX exhauster when there is a potential danger of explosion (dust or flammable gases in high concentrations).
