F&J - Model LV-14ME - Breathing Zone Low Volume Air Sampler (220 - 240 VAC)
From Air Samplers - Low Volume Air Samplers - Analog Low Volume Product Lines
Model LV-14ME is a cart mounted low volume air sampler with an adjustable, aluminum sampling gooseneck. The adjustable gooseneck permits sampling at heights varying from 122 cm - 213 cm (4' to 7') above floor level. The LV-14ME air sampler includes a 1/4 HP oil-less, carbon vane vacuum pump with a constant airflow regulator for use where a nearly constant airflow 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 head drop at all times permitting it to run cooler; thus extending its lifetime. The oil-less pump requires no lubrication to maintain optimal efficiency during its service life. The pump is mounted on a mobile cart with two rubber wheels to permit mobile transportation of the unit.
