Electric Confined Space Fans And Blowers

Electric confined space fans and blowers circulate a continuous supply of fresh air or to push out fumes. Raptor Supplies offers a huge array of confined space blowers / fans / ventilators and jet fans from brands like Allegro, Rafman, Americ, Air Systems International and Ecko. Americ confined space blowers and air exhausters are designed for applications requiring larger amounts of air output; ideal for use in Class 1 hazardous locations like pump rooms. These intrinsically safe blowers are powered by 1.5 HP pneumatic motors capable of providing a max airflow of 2063 CFM. They are enclosed in a dual-wall shell for absorbing impact. Allegro explosion-proof, confined space axial blowers are used in closed spaces with negligible ventilation. These blowers feature powerful & energy-efficient motors capable of producing a maximum airflow of 1636 CFM at 3320 RPM. They are ideal for the removal of smoke and harmful fumes with both positive & negative ventilation and are equipped with an integrated handle for portability. Electric confined space fans and blowers also include manhole entry kits.

Working Mechanism

  • Select a confined or limited space that originally has toxic gases.
  • Generally, the tanks or any confined space is ventilated from the bottom and through an opening on the top.
  • Attach the vent ducts to the fans or blowers and position them on a firm footing having minimum vibrations.
  • Use a pull switch or simply power on to activate a ventilator.
  • Eliminate the concentration of the present toxic gas below the appropriate atmospheric exposure level.

Features

Americ confined space blowers and air exhausters:

  • They are ideal for nonexplosive environments with greater air exchange.
  • They feature up to 5-hp motors to provide a max speed of 3495 rpm.
  • These electric confined space fans and blowers have a built-in handle for enhanced portability.
  • They offer a max flow rate of 9968 cfm and are available in voltage ratings of 115, 230 and 440V.

Allegro explosion proof blower fan:

  • They are used in closed spaces with negligible ventilation
  • These blowers feature powerful & energy-efficient motors capable of producing a maximum airflow of 1636 CFM at 3320 RPM.
  • They are ideal to remove smoke and harmful fumes with both positive & negative ventilation and are equipped with an integrated handle for portability.
  • These electric confined space fans and blowers also include manhole entry kits.

Air Systems International Confined Space Fan Kits:

  • These explosion-proof axial fans have polyethylene construction for lightweight and corrosion resistance.
  • They provide a free airflow rate of up to 2483 CFM and come included with a 10 feet cord and 25 feet conductive duct (on selected models), allowing easy transit during operation.
  • These OSHA-compliant confined space fans are available in red, black and orange colours.

Allegro AC Plastic Blowers:

  • They feature polyethylene construction for UV and chemical resistance and a steel powder-coated grill for protection against high moisture air.
  • These blowers have flexible ducting that allows passing through tight spaces for maximising accessibility and can be stored inside the canister itself to prevent the chances of damage to the ducting during transportation.
  • Their canisters are equipped with handles for easy portability on the job site, allowing the worker to instantly connect the canister to the blower.
  • These blowers have a quick-connect clipping system that allows the worker to instantly connect the canister to the blower.
  • The brand's lay flat ducting can be used as a supplement to further extend the range of the blower for quick and easy operation.

Americ Confined Space Fans:

  • Americ confined space fans feature dual wall shell design for protecting internal mechanisms & airflow.
  • They allow easy stacking over to save space in storage & work areas and are equipped with built-in handles for easy transit.

Frequently Asked Questions

How often should air be tested in a confined space?

To completely assess intoxicants or dangers, according to OSHA's standards, testing of the confined spaces should be performed at 4-foot intervals.

What types of ventilation can be used in confined spaces?

Forced or exhaust ventilation is suitable for confined spaces. Forced ventilation uses forced & fresh air to ventilate a confined space by displacing and diluting air, whereas exhaust ventilation uses exhaust to continuously remove contaminants at the source point.

How many air changes are required in a confined space?

According to the AIHA (American Industrial Hygiene Association), one air change every 3 minutes or 20 complete air changes per hour for a confined space is an acceptable practice. Ventilation of the confined space also depends on the product or material being ventilated from the area.

Are blowers better than fans?

  • Fans are electrical devices, while blowers are mechanical devices.
  • Fans consume less electricity. Blowers relatively intake more power.
  • Fans offer medium airflow depending on the capacity, whereas the blowers deliver better airflow than the fans.
