Polyurethane Foam Samplers (PUF)

The PUF (Polyurethane Foam) Sampler is a complete air sampling system designed to simultaneously collect suspended airborne particulates as well as trap airborne vapors at flow rates up to 280 liters per minute with the latest in technological advances for accurately measuring airborne particulates and vapors. PUF Sampler is equipped with a bypass blower motor arranged with an independent cooling fan. This feature permits the motor to operate at low sampling flow rates for extended periods without motor failure from overheating.

A dual chambered aluminum sampling module contains both fittering systems. The upper chamber supports the airborne particulate filler media in a circular filler holder. The lowe1 chamber encapsulates a glass cartridge which contains the Polyurethane Foam for vapor entrainment. Polyurethane foam or wet/dry granular solid media can be used individually or in combination. The dual chambered sampling 'P0dule is designed for easy access to both upper and lower media. The threaded lower canister is removed with the cartridge intact for immediate exchange. Filter support screens and module commponents are equipped with gaskets providing a leak proof seal during the sampling process.

Air flow rates are infinitely variable up to 280 liters per minute. The voltage variator adjustment screw alters the blower motor speed to achieve the desired flow rate. Air flow rate IS measured through the flow venturi utilizing a 0-100" Magnahelic Gage. Periodic calibration is necessa to maintain on-site sampling accuracy.

A Seven Day Mechanicat Timer is included as standard equipment and permits weekly scheduling with individual settings for each day and, 4 trippers to tum the sampler on and off. Any day or days may be omitted and day and night periods are distinctly marked. Other timers and programmers are available optionally to suit ny sampling requirement.
