For long term monitoring it is best to dedicate the pumps to reduce sampling time and avoid cross-contamination. Well Caps are designed for ease of use. The vented PVC cap has tubing and cable connectors on the underside; easy-to-attach drive line connector & discharge adaptor; and access holes as required. The cap slips easily onto 2” wells and may be sealed in place with an o-ring. They are available with or without a protective cover for the cap. Adaptors are available to fit 4” or other sizes of well.

The electronic controller uses 8 AA batteries that provide up to 30 hours of continuous use. It is fully automatic with preset sample modes to give a variety of useful drive and vent cycles. These can be further adjusted manually to optimize the flow. It allows faster purge rates and precise low flow to ensure a representative sample at100 ml/min or less when sampling for VOCs. The standard #466 gives up to160 psi and the 466HP offers 250 psi.

Air Compressors: an oil-less compressor is skid or cart mounted, providing up to 4.3 cfm and lift capability to 250 ft. (75 m). A portable 12v compressor, designed to operate using a vehicle’s battery is also available for shallow sampling and low flow applications.

In-Line Dryer: prevents moisture getting to the controller and pump. Used in-line between the pump controller and the air compressor.

Packers: minimize purge time by reducing the purge volume required and the cost of water disposal and labour.

Cart or Reel: for portable systems; compact field transportation.

Disposable Filters: .45µ, with 700 sq.cm filter area.

Well Caps, Protective Well Cover.
