Atlas Copco LT industrial piston compressor

Total reliability

LT compressors are exceptionally reliable, with the lowest operating temperatures in the industry, and offer quality air with low oil carryover. Built with durable and high-quality materials, they ensure quality performance and a long product lifetime.

Low running costs & easy maintenance

LT pistons offer low operational costs and are easy to maintain as components and services points are easily accessible.

Save floor space

Our LT compressor is ideal for customers who have limited space requirements. The compressor block, directly coupled to the motor, is manufactured using lightweight materials with excellent cooling characteristics.

LT oil-lubricated for two-stage compression

The LT two-stage oil-lubricated reciprocating compressor allows filtered air to enter only one cylinder. This low pressure cylinder feeds the second (high pressure) cylinder that can operate at a maximum pressure of 15, 20 or 30 bar (218, 290 or 435 psi) and with the following capacities:

15 bar (218 psi) from 3.1 to 11.7 l/s at 50 Hz, 7.6 to 23.1 cfm at 60 Hz.
20 bar (290 psi) from 2.1 to 18.0 l/s at 50 Hz, 5.7 to 44.3 cfm at 60 Hz.
30 bar (435 psi) from 2.5 to 17 l/s at 50 Hz, 6.6 to 41.7 cfm at 60 Hz.

Compression temperature is decreased between the two stages for increased compression efficiency.
