Unit Series 25 Drill Compressor Kit

The Sullair low pressure single stage rotary screw drill compressor delivers capacities and pressures from a range of 1200 cfm at 100 psig (34 m3/min at 7 bar) to 2000 cfm at 200 psig (56.6 m3/min at 14 bar). The drill air end is designed with an inlet control system and drive adapter to match up with drive choices. Multiple gear ratios with matched internal volume ratios dial in specific capacities and pressure for optimum performance.

Series 25 Features

  • Bare shafted drill airend
  • 2-Year warranty

Precision ground asymmetric profile delivers an optimal combination of capacity and power. Rotor speed range: 15 m/s to 50 m/s on male rotor tip.

Several built-in volume ratios offer a range of pressure ratios meeting specific application requirements.

AGMA Class 11 Gears allow for a variety of internal gear ratios contributing to design optimization and operation economy.

Heavy duty double-wall cast iron casing provide for structural rigidity, pressure integrity and low noise.

Drive Adaptor
Available drive adaptors (flywheel adaptors or base mounted) offer a convenient means to match up the air end with the drive unit.

The steel input shaft can be easily adapted/coupled to the driver with a variety of methods: keyed fit, mechanical locking or shrink- t coupling hub. Drivers used include natural gas and diesel engines; 1800 rpm, 2100 rpm motors; and variable speed drives.

The anti-friction bearings are manufactured from all-steel (no plastic or “yellow metal” cages) construction for superior durability. Tapered roller bearings absorb thrust and radial loads; while straight roller bearings handle opposite end radial loads both contributing to the optimal performance of the rotors, even in the harshest of conditions.

Capacity Controls Options
Capacity controls are an option offered on several models. These controls allow gases that have been only slightly compressed to bypass back into the suction head. Capacity can be manually adjusted or automatically controlled based on pressure signal.

Sullair Drill Compressor air ends are warranted for two years against defects in materials and workmanship.
