Maximum Reliability and Efficiency
For years, customers have depended on
Kaeser for reliable equipment and com-
plete compressed air system solutions.
Their research and development team
continues to produce industry-leading
compressor technology to meet virtually
any compressed air need. The new SX
series rotary screw compressors are no
exception.
These new 5 and 7.5 hp models
combine Kaeser's optimized Sigma Profile™
single-stage airend, high-efficiency
motors, heavy-duty construction and
simple modern controls into a com-
pressor built for years of reliable service.
A new cabinet design and component
layout reduce noise levels and footprint
while offering easier access during
preventive maintenance.
Manufactured in a rigorous quality
control program, Kaeser products are
made to provide years of reliable service
in the widest range of applications.
Maintenance Friendly Design
The SX is designed to be easily maintained and serviced. Maintenance friendly features include:
• Full access to all service items from one side
• Drive belt needs no adjustments
• Cartridge style 4 micron inlet filter
• Quick fluid change without pumping
• Spin on 10 micron fluid filter
• Spin on separator element
• Quick release fittings, drain and fill ports on separator vessel
• Cleanable cooler filter mat
• Side panel windows to view fluid level and test
SX-T with Integral Dryer
SX "T" models have integral refrigerated dryers, featuring plate-type heat exchangers and moisture separator, with stainless steel construction for long life. The refrigerant is CFC-free R134a. The dryer is controlled through the Sigma Control Basic and requires no additional electrical hook-up.

- A simple and reliable interface offers convenient pressure control and system monitoring with status displays and service indicators. Displays include discharge pressure and temperature, load and service hours as well as fault indicators.
- Kaeser's power-saving, proprietary airend design delivers pressures up to 217 psig. Kaeser uses a newly designed airend for this SX series. It is precision-machined to close tolerances and optomized in size and profile to match the low airend speeds with their best specific performance, up to 20% less energy than comparable airends.
- High-efficiency, totally enclosed, fan cooled (TEFC) motors with Class F insulation are standard for long life in harsh environments. Tri-voltage 208-230/460 or 575 V, 3-phase, 60 Hz is standard. Other voltages are available. EPAct compliant. Magnetic Wye-Delta reduced voltage starters ensure low starting current and smooth acceleration.
- Kaesar combines an over-sized cyclone separator vessel (ASME or CRN) with a convenient spin-on coalescing filter for superior fluid separation and exceptionally low carry-over (3 ppm or less). This results in less maintenance and better downstream air quality.
- All units are filled with Kaeser Premium Fluid to cool, clean, and lubricate the airend. A thermostatically controlled combination valve ensures perfect fluid temperature regulation and incorporates a cooler by-pass and fluid filter. Main air and fluid lines are made of rigid pipe with flexible pipe connections. The 10 micron spin-on fluid filter extends fluid life and protects the airend.
- Superior cabinet design reduces noise and footprint while offering easy access for service. A heavy-duty metal enclosure with a durable powder-coated finish keeps noise in but dirt and dust out. Thick sound insulation keeps noise levels as low as 62 dB(A), more than 10 dB(A) quieter than comparable units.
- All maintenance items are accessible behind one easily removed locking panel. The fluid level indicator is visible through a conveniently placed window in the service side panel.
- The double-flow cooling fan produces the cooling air flow for the drive motor on one side and the cooling air for the package on the other. The crescent-shaped fan blades help to futher reduce sound emissions. Air is drawn into separate cooling zones for the drive motor and coolers. This "split cooling" design eliminates pre-heating, increasing cooling efficiency without increasing power consumption. Cooler temperatures also promote longer lubricant and motor life. Cooling air is exhausted through a side port at the top of the cabinet. Ducting this air enables heat recovery for significant energy savings.
