Air Sampling Pumps and Accessories

TJ Environmental offers high quality air sampling pumps. The JD8T and JD16T sampling pumps are designed by experienced field staff to withstand the rigors of site work, particularly in the asbestos removal industry.

Air Sampling Pump They are constructed from epoxy-coated aluminium and, as a result, are strong, rigid and rustproof. Flow control is via a needle valve, which ensures a stable flow rate throughout the sampling range. Pumps are equipped with NiMH battery packs. The batteries will not develop a memory if charged before complete discharge and have a longer life than lead acid batteries.

Listed below are the standard specifications of both pumps, however, there are a number of optional extras available including preset and programmable timers, flow meters and active flow control. Pumps can also be built or modified to customer’s own requirements.
