Venturi Blower

Venturi Blowers Venturi Blower Anti Static Grounding Clamp
Click on main image to expand

Venturi blowers are a great way to create air movement through confined spaces. They simply attach to a compressor line and the unit uses the Venturi principle of passing high velocity air through small holes in an outer ring. This then creates an air flow through the cone which then drags far more air with it, creating a very effective flow.

This is very versatile method but can be quite noisy as it does sound a bit like a jet engine so needs to be positioned away from the workforce.

This can be used as a stand-alone item to simply cause a through airflow or be linked to trunking to introduce clean air into the system from outside of the confined space.

These units can be much more productive than a traditional fan and do not pose the same electrical issues.

An optional grounding clamp is available for use with these units for situations where static may cause a problem.

The Clarke Contractor air mover is a high performance 300mm, 110v ventilator fan. Stale air is rapidly extracted at 3900 m3/h (at optimum efficiency) to give a cleaner working environment. It is suitable for use with:

  • 110V generator
  • 110V isolating transformer
  • 110V site supply
  • 230V generator via a 110V transformer.

The ventilator fan can be used with 300mm diameter retractable ducting which is available in 5m lengths.

The fan is not ATEX rated and must not be used in explosive atmospheres such as in the presence of flammable liquids, gasses or dust.

Click on main image to expand

The VAF-300 is a 110v ventilator and extractor fan that can move up to up to 3400 m³/hr, using 300mm diameter ducting which can be joined together to form longer lengths.

The VAF-300 works on positive and negative airflow and can be used as a stand alone fan for cooling, drying or used with the ducting to inject fresh air or extract contaminated air from confined spaces.

The fan is not ATEX rated and so must only be used to force air into an explosive atmosphere with the unit being up wind, away from the access hatch for confined space use. It must not be used to extract from a potentially explosive atmosphere.

The fan body is made from a dual wall polythene rotational moulding and can withstand the rigours of an industrial setting. The fans can be easily stacked on top of one another for storage and during operation (max. 3 high) which reduces the floor space required.
