Low Volume Air Sampler

Category: Worker Health & Safety > Engineering Controls > Air Monitoring
Reference # : Model No : F&J Model LV-1D

Model LV-1D is a low volume air sampler consisting of a 1/4 H.P. oil-less, carbon vane vacuum pump with a flow meter, a vacuum gauge and a constant air flow regulator for use where a nearly constant air flow is desirable. The regulator holds a constant pressure drop across an in-line orifice by varying the flow through a bypass valve into the pump. This system allows the pump to work at a minimum pressure drop at all times by permitting it to run cooler; thus extending its service life. The oil-less pump requires no lubrication to maintain optimal efficiency during it service life. The pump is mounted on a base with four rubber feet. A handle is provided on the chassis to facilitate its transportation. The LV-1D is distinguished from the LV-1 air sampler in that the flow meter and vacuum gauge are mounted on a quick disconnect plastic manifold on top of the motor that facilitates maintenance operations. The typical operating flow range is 0.35 to 3.5 CFM (10 – 100 LPM).


Constant air flow regulator adjustable by user. Chassis mounted ON-OFF switch with fuse protection. Durable plastic combination filter holder with quick disconnect fittings. Internal intake and exhaust mufflers.
