When working in a confined space situation it is important to ensure there is the appropriate amount of ventilation, either by adding fresh air or exracting contaminated air from the confined space work area.
Ventilation is used to remove the unpleasant smells and excessive moisture by introducing outside air, to keep the confined space air circulating, ventilation helps prevent stagnation of the interior air allowing for a free flow of fresh air.
Our range of Allegro blowers and extractors below will allow you to ventilate or purge the air in your confined space as required.

Compressed air or saturated steam is the power source for our Venturi Blower line. Small volumes of high velocity air (from the compressed air source) run through the casting and out the nozzle jets, creating a venturi or pulling action that creates large volumes of air through the Venturi and out the air diffuser.
A 1/2” hose with a “crows foot” connection is recommended from your air supply source to the side inlet connection. The compressor size required can be determined by checking the chart on air consumed at various inlet pressures. Operate this Venturi Blower on air or steam lines limited to 140 psi.
