Dresser-Rand offers new, refurbished and remanufactured Spiraxial atomizing air
compressors for a variety of
market applications. Dresser-Rand
purchased the Spiraxial compressor
product line in 1998 from Dresser
Roots and is now the OEM.
The design of this unique compressor relies on nearly half a century of
experience. It was developed for marine
deballast, as an atomizing compressor for power generation applications,
and for use in a variety of commercial
applications, such as tank aeration and
fly ash conveying. It is well-known for its
rugged construction, long life and easy accessibility.
Mode of operation
As a positive displacement compressor, the Spiraxial compressor displaces a specific
amount of air with each revolution. Each rotor is a single-screw thread. As the two
rotors intermesh, they rotate in opposite directions. The inlet cavity is positioned so
that the advancing helix closes off the pocket of air after it has filled. As the helix
advances, the pocket squeezes the air against the discharge end headplate. After the
required degree of compression has been reached, the rotor uncovers a
discharge port and compressed air is released into a plenum in the headplate.
New units/overhauls/parts
New units are available for immediate delivery from our facility and are mechanically
and performance tested before shipment. Export boxing and shipment are available.
Overhaul kits are available and include bearings, seals, gaskets, O-rings and hardware.
Overhauls are performed at our service center in Chesapeake, Virginia, and each overhaul includes a performance and mechanical test prior to shipment.
All parts for the Spiraxial 51/4 x 63/4 LAL-SP-SVP atomizing air compressor are available
at our Chesapeake service center.
