Screw compressor reduces costs and noise

The L80 also delivers noise levels of 69dB(A), meaning that it is easy to stand next to the compressor and have a conversation, with no need for users to wear ear protection.

CompAir has released the L80 lubricated screw compressor.

The super-efficient machine is an extension of CompAir's popular 75kW class and gives users over 7% more air (14.72m3/min) while maintaining a lower power input.

Other tangible benefits include low operation costs, reduced noise levels, a small footprint and easy maintenance.

The L80 incorporates the premium EK230 air end and an IP55 energy saving motor.

Coupled with much lower rotational speeds the result is an increase in efficiency and energy savings of up to 8%.

The L80 also delivers noise levels of 69dB(A), meaning that it is easy to stand next to the compressor and have a conversation, with no need for users to wear ear protection.

Coupled with the small footprint, this means that the compressor does not need to be relegated to a distant compressor house, but can be located right next to the air's point of use, which will reduce pipework and the chances of leaks and pressure drops.

Jeremy Sykes from CompAir says: "The new L80 compressor offers greater performance for the same input as a typical 75kW machine".

"To get this kind of performance users would until now have needed to buy a larger machine having in excess of an 30% larger footprint, and higher power usage".

"With the L80's motor qualifying for the government's enhanced capital allowance due to its super efficiency, it is an extra incentive to buy not just on performance but satisfy the environmental agenda also".

"While some believe that all machines with similar size motors have similar performance, CompAir has been working hard to get more out from the electrical energy we put in - the L80 is another example of the success of that approach".

"This just shows how technology is moving on and underlines the importance of regularly reviewing your compressed air solution to ensure it is operating at maximum efficiency".

Other benefits of the new L80 include electronic controls which combine efficient monitoring with a user-friendly menu, superior access for maintenance through large hinged doors and an effective cooling air filter which keeps the unit clean and assures the long life of all filters.

As an optional benefit, the L80 can be fitted with an energy recovery module which takes heat produced in the compression process and re-uses it elsewhere in the factory.

This can lead to significant savings.

For example, it can heat 1200 litres of water per hour, up to 65C which would lead to annual savings of nearly GBP 8000 based on 2000 running hours.

The L80 can also be supplied with an built-in dryer giving a true integrated compressed air solution in a very compact space.

The L80 comes with CompAir's Assure free extended warranty scheme as standard.

Based on a 'working when you are' approach instead of the year-long industry standard warranty, the Assure programme provides up to 44,000 operating hours cover, providing the machine is serviced according to the manufacturer's schedule.

The Assure warranties are valid for resale across the globe.
