HL Series

Power class: 2.2–45 kW

The well-conceived modular principle of the HL series makes it extremely versatile and it can be used for all applications up to 40 bars, even under the toughest industrial conditions.
It sets standards in terms of quality, operating reliability, service life and operating convenience.
ALUP HL piston compressors are renowned for economical compressed air production also in three-shift continuous operation.
In combination with the big, high performance fan V-belt disc, the free-standing grey cast iron cylinders which are equipped with large cooling fins form a highly efficient cooling system for extremely low plant temperatures and maximum compressed air quality.
Other important advantages of the HL concept are:
 
Low rotational speed and piston speed
Generously dimensioned intake and pressure valves
as well as intake lines for high overall plant efficiency.
