F&J - Model LV2234 -Analog Low Volume Air Sampler (100 - 120 VAC)
The Model LV2234 is a low volume air sampler consisting of a ¾ HP oil-less, carbon vane vacuum pump with a flowmeter, vacuum gauge and 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 pressure drop at all times, permitting it to run cooler; thus extending its service life. The oil-less pump requires no lubrication to maintain optimal efficiency during its service life. The p ump is mounted on a removable base plate, which can be secured within the GFCI protected aluminum environmental weatherhouse, Model WH-3, having an enclosure rating of IPX3. An optional mechanical volume totalizer is available for the LV2234 air sampler.
The LV2234 Air Sampling System is designed for continuous outdoor operation. Please consult the product specification for the design temperature range and the installation category.
The typical operating flow range is 1 to 6 CFM (30 to 170 LPM)
