Metcal, a division of OK International, has introduced a compact and truly portable two-arm fume extraction system that combines strong fan performance with efficient filtration and quiet, flexible operation. Metcal enlisted the fume extraction expertise of Impell, another OK International division, to develop the BVX-200 fume extraction system.

The stylish BVX-200 builds on the success of Metcal's existing BVX-100 single arm system. The new unit features the same motor as the single-armed model, but it has an innovative one- stage impeller design that provides more than double the total free-blowing airflow.

A proprietary impeller was chosen over an off- the-shelf design to maximise performance while keeping the size and weight to a minimum. The result is a truly portable unit that can be easily transported by one person without the strain induced by larger units.

Maximum free-blowing airflow is rated at 250 m3/h, with maximum suction force at 850 Pa. This is the best suction rating in the unit's class and the highest offered by such a compact and portable system. The 850 Pa rating provides ample capability in reserve to handle any clogging that occurs during normal filter life.

The unit is compact enough to be located under, or next to, the workbench. It has been designed specifically to be located off the benchtop to maximise the available working area without obstructing the space underneath. It can be used with either two 2 in. (50 mm) diameter hoses and BVX arms, or one 2.5 in. (67 mm) hose and an Omniflex arm. The single arm offers a 50 percent higher airflow than one of the smaller arms, with airflows per arm rated at 75 and 110 m3/h, respectively.
