F&J - Model LV-14MHT - Low Volume Air Sampler (100 - 120 VAC)
From Air Samplers - Low Volume Air Samplers - Analog Low Volume Product Lines
Model LV-14MHT is a heavy-duty hand truck mounted low volume air sampler with an adjustable, aluminum sampling gooseneck. The adjustable gooseneck permits sampling at heights varying from 4′ to 7′ (122 cm – 213 cm) above floor level.
The LV-14MHT 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 by 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.
The typical operating flow range is 1 to 3.5 CFM (10 – 100 LPM).
