The Air Measuring Kit is used to measure the uphole bailing velocity of the air being delivered by the compressor with the drillbit and drillrods currently in use on the machine, and to establish if the compressor system is operating normally.

It is also used to determine if the delivered velocity bears a true relation to the rated capacity of the compressor.

The kit comprises of an orifice flow tube with thread adaptors to suite tricone drillbits commonly in use.  A number of orifice plates are provided that will allow for the measurement of airflow with virtually any size of drillbit nozzles.  Two air pressure gauges for high and low pressure systems are provided to allow for the testing of both DTH and rotary drillrigs.

The kit is supplied with a set of tables and example calculations to allow for the simple determination of the airflow with the drillbit nozzles or hammer choke in use.

Drilling Project Services will if necessary assist the purchaser of these units in calculating the airflow using by making our e-mail address available.
