Need nitrogen? Add the LZ

Are you a frequent user of nitrogen? The Atlas Copco LZ is the high-performance, cost-saving foundation of your nitrogen generation system. The oil-free LZ doesn’t require additional filtration equipment.

As a result, the LZ gives you a more compact footprint, lower maintenance and minimized downtime. Because the LZ doesn’t compromise the adsorbent of the nitrogen generator, your system will last longer as well.

Premium Performance

Piston compressors have always presented a compelling offer: robust, low maintenance and energy efficient. However, this strong performance typically came with high noise levels and few control options. The Atlas Copco LZ eliminates this trade-off. 

Different power options
5.5 - 15 KW
Pressure levels
4 - 10 bar
Electric potential options
230 / 400 / 460V

Adapted to match your needs

The LZ oil-free piston compressors are reliable and flexible. 

Meet the full range with different power (5.5–15KW), pressure (4–10 bar) and electric potential (230/400/460V) options. Choose from flexible integration options: pack and full feature, base and tank mounted versions available (for the LZ 7/10).

High energy efficiency

The direct driven LZ comes with a number of innovations like a one-bearing motor, load/stop technology… to reduce energy consumption to an impressive minimum.

Quiet operation

Thanks to its sound-insulating canopy, the LZ achieves noise levels as low as 71 db(A), allowing installation to be close to the point of use.

Do you still use nitrogen bottles?

Atlas Copco nitrogen generation systems combine a compressor with a nitrogen generator to create the sustainable and cost-efficient alternative to cylinders or bulk supply. 

More sustainable
A nitrogen generation system provides an independent supply of nitrogen when needed and at the lowest cost, eliminating ordering, transportation, storage and delivery expenses.
