Rotary Screw Air Compressors with Dryers - AIRTOWER Compressed Air Station

• Plug and play:
  Our all-in-one compressed air systems require minimal effort when it comes to piping and installation. Simply connect the station to a power supply and your compressed air network and that’s it – you’re ready to go!
• Protected from corrosion damage:
  Thanks to the integrated refrigeration dryer, AIRTOWER systems deliver high-quality compressed air that protects your tools and equipment from corrosion damage.
• Simple maintenance:
  All maintenance points are easily accessible by lifting off the lightweight, removable enclosure constructed from rotomolded polyethylene. The electronic condensate drain can be inspected via a grille. Maintenance is simple and effective.

Buying a compressor, dryer, and tank as standalone units creates more than just a bigger parts list. It creates more installation work, more wiring runs, more potential leak points, and more touchpoints for a technician every service cycle. 

The AIRTOWER eliminates that problem by housing the rotary screw airend, refrigerated dryer, and receiver tank inside a single pre-engineered, pre-wired enclosure. You get a rotary screw air compressor with a dryer designed to work as a system. The airend, cooling circuit, and dryer share a thermal management system, which means the unit runs more efficiently than a field-assembled equivalent at the same horsepower. 

This also matters for air quality. Moisture in compressed air lines corrodes tooling, contaminates spray finishes, and can compromise pneumatic controls. Because the AIRTOWER's refrigerated dryer is sized and matched to the airend from the factory, it consistently achieves a 37°F pressure dew point across the entire rated flow range.

Light industrial environments are not lab conditions. Dust, temperature swings, vibration from nearby machinery, and intermittent heavy draws are daily realities in woodworking shops, fabrication floors, and auto service bays. Our rotary screw air compressors with dryers can handle it all.

The AIRTOWER's double-walled roto-molded polyethylene enclosure withstands ambient abuse that would crack or corrode a sheet metal cabinet. The IP 54-rated control cabinet protects electrical components from dust ingress and water splashes, a standard that matters when compressed air and shop-cleaning equipment share the same space.

The IE3 premium efficiency motor adds a practical layer of protection here, too. Its insulation class F rating gives the motor a built-in thermal buffer, so it handles the kind of starts and stops common in shops running intermittent pneumatic tools without prematurely wearing down the motor windings.

Purchase price is one number. Operating cost over five or 10 years is a different conversation.

Kaeser's SIGMA PROFILE rotors use 10 to 20 percent less energy than conventional rotor profiles at the same flow output. For a shop running a 7.5 hp compressor at typical duty cycles, that efficiency margin translates into real savings on the electricity bill over time. The maintenance-free elastic belt drive removes re-tensioning labor from the service schedule entirely, and the zero-loss ECO DRAIN condensate system means you're not continuously venting compressed air just to remove water, a common hidden loss in time-delayed drain systems.

Our SIGMA CONTROL logs operational data to an SD card and supports Ethernet connectivity, so service history and performance trends are available without digging through manual logbooks. That documentation supports faster diagnostics and helps you plan preventive maintenance before a failure interrupts production.

The AIRTOWER gives light industrial operations a rotary screw compressor with an integrated air dryer that installs quickly, runs quietly at 69–70 dB(A), and needs minimal attention between service intervals. Connect power, connect your distribution line, and you have clean, dry compressed air.
