F&J Model LV-1

Description

Model LV-1 is a low volume air sampler consisting of a ¼ HP oil-less, carbon vane vacuum pump with a flow meter, vacuum gauge and 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 in to 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 pump is mounted on a base with four rubber feet. A handle is provided on the chassis to facilitate its transportation. The LV-1 Air Sampling System is designed for continuous indoor use. Please consult the product specifications for the design temperature and the installation category.
The typical operating flow range is 1 to 3 CFM (10 – 100 LPM).

FEATURES:

• Constant air flow regulator adjustable by user.
• Chassis mounted ON-OFF switch with fuse protection.
• Durable oil-less carbon vane pump designed for continuous use.
• Internal intake and exhaust mufflers.
• Rotometer and Vacuum gauge.
• 110 – 120VAC, 50/60Hz; single phase.
