F&J - Model GAS-2234E Global -Low Volume Air Sampler (220 - 240 VAC)
The Model GAS-2234E Global Air Sampling System is a microprocessor controlled low-volume air sampler consisting of an 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 service life. The oil-less pump requires no lubrication to maintain optimal efficiency during its service life. The pump 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.temperatures as high as 60°C (140°F).
The GAS-2234E utilizes a bright VFD that has four (4) lines by 24 characters and utilizes wide temperature range electronic components for use in extreme ambient conditions.
The GAS-2234E Global Air Sampling System is designed for continuous outdoor use. Please consult the product specifications for the design temperature range and the installation category.
The typical operating flow range is 1 to 8.5 CFM (28 – 240LPM).
