Working in Confined Spaces

The portable Miniveyor Air VAF series fans from VAF Air work on both positive and negative air flow, so are equally at home extracting as well as blowing and are great for ventilating confined work spaces.

When working in confined spaces it is recommended that you change the air at least 20 times per hour, or once every 3 minutes, and that you not only extract the air but also utilize a blower to push clean air into the work space. To use this recommended method, you would need 2 or more openings to your confined work space and employ 2 fans. If you only have 1 opening, then you should use positive airflow and use the fan to blow air into the confined work space.

The Miniveyor Air VAF series vane axial fans and ventilators form VAF Air Ltd are the professional choice for portable dust and welding fume extraction.

Designed with a twin wall, rotationally moulded fan body, made from high density polythene, means the products can absorb bangs frequently experienced with industrial use, eliminating costly maintenance procedures. Compare this with conventional metal bodied fans that typically don’t last very long in the workplace, as the sheet metal bodied fans tend to dent easily when knocked, so they will need replacing. The plastic moulded fans from VAF Air are highly resistant so they can last a much longer time. Additionally, all the parts are replaceable so if anything does get damaged then they can be changed easily.

New for 2017 is the VAF-EF400 which is designed to push large volumes of air into a hard to reach areas or through ducting. Driven by a precision balanced, cast aluminium 17 blade turbo impeller, the VAF-EF400 delivers a whopping 10,360 m³ of air per hour.
