We are thrilled to announce that the team at Capital Compressors has just completed the sale, delivery, and successful installation of a new Westair Variable Speed Drive (VSD) Air Compressor for one of our valued clients located in Queanbeyan!
Westair Pneumatic Systems, in partnership with Capital Compressors, has been providing advanced energy-saving compressed air solutions throughout the Canberra and surrounding regions. We offer an extensive range of energy-saving solutions, including scroll air compressors, variable speed drive air compressors, and efficient direct-drive fixed-speed rotary screw compressors, available in both oil-injected and oil-free configurations. Both Westair and Capital Compressors is committed to delivering advanced energy-saving compressed air solutions, focusing on research and development and utilizing top-class components.
Benefits of the Westair SCR APM Variable Speed Drive Air Compressors - The Westair SCR APM series of rotary screw air compressors with Variable Speed Drive (VSD) technology offers significant advantages, especially for businesses looking to reduce energy costs.
Advanced Energy Saving: The SCR APM range is designed to provide advanced energy-saving compressed air solutions. Many businesses attribute 15-20% of their total energy costs to generating compressed air, making a high-efficiency system a smart consideration.
Significant Power Savings: Businesses can save up to 60% on their compressed power costs compared to an equivalent fixed-speed compressor. The Westair APM range only produces the air needed, leading to significant savings, especially when air demand varies throughout the day.
More Air per Kilowatt: The new oversized compression airend delivers 10-15% more air per kilowatt. This efficiency can even allow for the use of a lower kW compressor to meet peak air demand. For instance, a Westair SCR50APM-8 with 37kW can deliver
7.2m3/min, which might otherwise require a more costly 45kW or 55kW VSD compressor from other companies.
No Offload Running: When the compressor reaches the desired pressure, it stops, eliminating energy waste from offload running. The Interior Permanent Magnet (IPM) motor, used in the SCR-PM series, has an unlimited start-stop ability, which dramatically reduces total run hours and power usage, unlike AC induction motors found in most VFD compressors.
Lower RPM: The SCR EPM range boasts an average of 40-50% lower maximum RPM compared to competitors, contributing to increased efficiency.
Quiet Operation: These compressors are designed for quiet noise levels, reduced by up to 6dB(A) compared to previous models, making them among the quietest VSD compressors in their class and ideal for maintaining a safe workplace.
We are confident that our client will experience significant energy savings and reliable performance with their new Westair VSD Air Compressor!
