• Suitable for harsh environments.
• High-efficiency drive arrangement; no coupling or slippage losses.
• Standard up to 46˚C/115˚F and for high ambient version 55˚C/131˚F.

IE3 Premium Efficiency electrical motors
• IP55, insulation Class F, B rise.
• Non-drive side bearing greased for life.
• Designed for continuous operation in harsh environments.

Robust spin-on oil filter
• High-efficiency, removing 300% smaller particles than a conventional filter.
• Integrated bypass valve with the oil filter.

SIL Smart inlet lock system for GA VSD compressors
• Superior designed vacuum and air pressure controlled valve with minimal pressure drop and no springs.
• Smart stop/start which eliminates back-pressure oil vapor.

Separate oversized oil cooler and aftercooler
• Low element outlet temperatures, ensuring long oil lifetime.
• Removal of nearly 100% condensate by integrated mechanical separator.
• No consumables.
• Eliminates possibility of thermal shocks in coolers.
 
Specifications

* Unit performance measured according to ISO 1217, Annex C, Edition 4:2009.
Reference conditions:
• Absolute inlet pressure 1 bar (14.5 psi)
• Intake air temperature 20°C, 68°F

FAD is measured at the following working pressures:
• 7.5 bar versions at 7 bar
• 8.5 bar versions at 8 bar
• 10 bar versions at 9.5 bar
• 10.5 bar serion at 10 bar
• 13 bar versions at 12.5 bar
** A-weighted emission sound pressure level at the work station, Lp WSA (re 20 μPa) dB (with uncertainty 3 dB).
Values determined according to noise level test code ISO 2151 and noise measurement standard ISO 9614.
Pressure dew point of integrated refrigerant dryer at reference conditions: 2ºC to 3ºC, 36°F to 37°F.

Lowest lifecycle costs and peace of mind
• No extra installation costs.
• Saving floor space.
• Use of energy-efficient, environmentally friendly refrigerant R410A reduces operating costs and stands for zero ozone depletion.
• Heat exchanger cross-flow technology with low pressure drop, saving energy and costs.
• Zero waste of compressed air thanks to no-loss condensate drain.
• Advanced control functions ensure dry air under all circumstances and prevent freezing at low load.
• Pressure dew point of 3°C (100% relative humidity at 20°C).

Integrated Purity

The optional UD+ filter and integrated refrigerant air dryer (IFD) efficiently remove moisture, aerosols and dirt particles to protect your investment. The UD+ filter has a 40% lower pressure drop than the conventional DD+/PD+ filter combination. It saves space and reduces energy costs. Using
only 1 single filter it is possible to reach quality class 1.4.2 according to ISO 8573-1:2010.

Optimize your system
Some applications may need or may benefit from additional options and more refined control/air treatment systems. To meet these needs, Atlas has developed options and easily integrated compatible equipment.

Integrated Energy Recovery

As much as 90% of the electrical energy used by a compressed air solution is converted into heat. Using Atlas ’s integrated energy recovery systems, it is feasible to recover up to 75% of that power input as hot air or hot water without any influence on the compressor’s performance. Through efficient usage of the recovered energy, you bring about important energy cost savings and obtain a high return on investment.

Energy Recovery applications
• Auxiliary or main heating of warehouses, workshops etc.
• Industrial process heating.
• Water heating for laundries, industrial cleaning and sanitary facilities.
• Canteens and large kitchens.
• Food industry.
• Chemical and pharmaceutical industries.
• Drying processes.
