The Sullair combo compressor has been developed predominantly to meet the needs of demanding drilling and exploration applications. With the unique ability to deliver both high-capacity/high-pressure (1150cfm/350psig) and lower-capacity/ higher-pressure (900cfm/500psig) compressed air, the Sullair combo abolishes the need for an additional booster compressor in some instances.

Drill sites are commonly equipped with low-pressure compressors for primary drilling, plus a booster compressor to tackle the harsher drilling conditions. While a necessity, this method results in wasted resources and costly downtime associated with interchanging compressed air lines and transporting both units to and from site.

Easy continuous drilling

The Sullair combo enables continuous drilling. With a simple flick of a switch, the Sullair combo converts from the lower pressure unit to a high-pressure unit, allowing the operator to instantly address varying drilling conditions. The ability to make this immediate adaptation greatly assists drillers; with the current demands in the metals and coal industry, drillers will truly enjoy the full benefits this machine has to offer.

The dual functionality of the Sullair combo is founded on Sullair’s innovative rotary screw spiral valve air-end. This innovative spiral-valve technology built into the air-end controls a precision network of bypass porting within the first stage of the two-stage compressor. By controlling the delivery of air to the rotary screw air-end, the effective rotor length and compression volume is modified, enabling the delivery of compressed air at the selected capacity and pressure.

Powered by a Caterpillar C-15ATAAC diesel engine and enclosed in sturdy sheet metal housing, the Sullair combo boasts several specialised design features. An ambient cooling unit draws outside ambient air through the compressor via an efficient engine-mounted fan, while a compressor protection circuit monitors temperature, and coolant and fuel levels. 

Unlike competing compressor offerings, the performance specifications of Sullair’s compressors are based on continuous operation, not a best-case scenario. This is particularly important in the drilling industry, as the compressors often operate on remote drill sites where breakdowns are crippling, and reliability is paramount.
