LV-28BMHT - The Model LV28BMHT heavy duty hand truck mounted mobile low volume air sampler designed for outdoor use with an analog flowmeter and an adjustable, aluminum sampling gooseneck. The adjustable gooseneck permits sampling at heights varying from 4’ to 7’ above floor level. The air sampler is contained in a powder coat painted environmental enclosure mounted ~ 4 inches above ground level.
It includes an oil-less, carbon vane vacuum pump with a constant airflow regulator for use where a nearly constant airflow is desirable and holds a constant pressure drop across an in-line orifice by varying the flow through a bypass valve into the pump. The pump is mounted on a rugged mobile hand truck with two 10.5” diameter pneumatic tires to facilitate mobile transportation of the unit.
The LV28BMHT is designed for continuous indoor or outdoor use. Please consult the product specifications for the design temperature range and the installation category.
The typical operating flow range is 0.5 to 3.5 CFM (14-110 LPM)
