8" / 20.32 cm diameter axial fan. It has the particularity to be light and compact. The flexible duct is stored in a removable rigid compartment that is connected to the fan by quick-clips. This fan, also known as a blower, can either extract (purge) or ventilate a confined space depending on the orientation chosen by the user.

Manufacturer's code: 9533-12, 9522-25 or 9533-50.
Also available for 220V voltages by special order.

This type of blower is used to ventilate confined spaces that do not have an explosion hazard. If this is the case, please refer to the following item RA9548-25EX.

In practice, the contaminated gases are extracted first, then a reading is taken with a gas detector equipped with a sampling pump (see DETEC4GC) and if everything is correct, the fan is reversed to push fresh air into the confined space. Because of the hazards of toxic vapours or particles in a confined space, be sure to equip your workers with gas detectors even if you have purged and ventilated the confined space.

The housing is made of lightweight polyethylene and is resistant to corrosion, UV light and most chemicals. This compact blower is super quiet according to the manufacturer. However, it recommends wearing hearing protection for people near the blower in its instruction manual. The blower has nine polypropylene blades, a powdered steel grill and a carrying handle moulded into the blower. This blower is also equipped with a single-phase electric motor.

The lower housing provides safe and convenient storage of electrical components. Both sides of the fan have connection rings for attaching ductwork. This makes it easy to switch to exhaust or ventilation mode quickly depending on which side you choose.

Installation Tips:

The manufacturer recommends that the fan be installed more than 5 feet away from the hole entrance. To choose the safest location for you. Ensure the wind is flowing in the right direction. When venting the place, so that the fumes disperse with the help of the wind without it returning to you. In the same way during the ventilation, place the blower with your back to the wind. This way you will avoid gas mixtures expelled from the enclosed space.

If you wish to replace your ventilation duct, two lengths are available: 15 feet / 4.57 m or 25 feet / 7.62 m. You will find them under the reference RA9500-815 or RA9500-825. If your blower needs a small repair, you can also consult the list of components under the download tab.
