Rotary Screw Air CompressorsTWO-STAGE


18-55kW, Two-Stage, Direct Drive, Fixed Speed or VSD with a Permanent Magnet Motor BSC have produced the ultimate high efficiency compressor package for the Australian market. The result is the impressive all new BMF two-stage VSD Permanent Magnet compressor. This 2 stage compressor range incorporates an impressive list of energy-saving and high-efficiency features that will become the benchmark for all other compressor companies to aspire to. Two-Stage rotary screw air compressors have been available for over 20 years. Until now, this technology has typically only been available to buyers of 90kW and above models. Westair can now supply these two-stage high efficiency compressors starting from just 18.5kw. Starting from such a low KW size enables a much larger industrial customer base to be able to benefit from such incredible energy saving efficient technology.

THE ULTIMATE ENERGY SAVING 2 Stage VSD Drive Air Compressor

TWO-STAGE

Energy savings of up to 50% Unique Benefits of the BSC Two-Stage Series:

Save Up to 50% in power costs - Compared to an equivalent fixed speed compressor 15-25% more air per kW - Compared to many other rotary screw compressors - So efficient you can drop down a motor size compared to a single stage airend No Off Load Running - When compressor is up to pressure, it stops with no off load running Pay Back from Energy Savings in as little as 1-2 years - Depending on a range of variables such as electricity cost, compressor size and air demand Better Quality Air - Less heat generated during compression improves air treatment effectiveness Long Airend Life Design - Two-Stage compression reduces load on the bearings and greatly extends their life Low RPM Airend/Motor - Average of 40-50% lower max RPM than our competitors Create the Ultimate High Efficiency System - Depending on your air demand, choose from: o Variable Speed Drive VSD with a Permanent Magnet motor o Fixed Speed for steady air demands o Both – A fixed speed with a VSD model acting as a trim compressor

UP TO 25% MORE AIR PER KILOWATT! The BSC two-stage airend produces around 15-25% more air than many comparable single stage air compressors airends. With the extra flow available, it is possible to use a smaller kW compressor and save on power. Example: If your peak air demand is 9.5 m3/min (335cfm) at 8 Bar, A Westair BMF45II-8 with a 45 kw motor will deliver the air you require. Other compressor companies could suggest a more costly 55 kw or even a 75 kw compressor to deliver the air to meet your peak demand. Just another example of how Westair is committed to delivering Advanced Energy Saving Compressed Air Solutions

VSD-High Efficiency Permanent Magnet Drive Motor The Interior Permanent Magnet (IPM) motor uses DC power via an inverter to seamlessly speed up and slow down the compressor to match your air demands. After the compressor reaches its off load pressure the motor stops with no off load running. AC induction motors found on most variable frequency drive compressors are limited to the number of times per hour they can stop/start, and therefore, cannot match the efficiency of the IPM motor. The BMF series has an unlimited start-stop ability which can dramatically reduce both total run hours, and power usage.

Highest IPM Motor • Soft start • Variable range of 30-100% • No off load running (22kw – 75kw) • Can dramatically reduce running hours & power consumption • Direct Drive (1:1 ratio) – eliminates gearing or transmission losses Special Dual Housing Oil-Cooled Motor The airend lubricant also cools the motor in a design in which the two housings are incorporated into one, with space left for an oil channel between the inner and outer housing. This design helps cool the motor more efficiently than the traditional air cooling fan system and reduces power consumption (22kw – 75kw). The airend and motor use a simple morse connection which is easy for installation and dismantling.

A two-stage airend offers real world advantages to every compressor installation The BSC Two Stage essentially has two airends, one large low pressure airend, and one smaller high pressure airend, both integrated within the same airend “block”. Atmospheric air enters the low pressure airend and is pressurised to around 50% of the final pressure. The pressurised air then enters the second ‘high pressure boosting airend’ where air is compressed to the final pressure. The lower compression ratios in each airend offer superior volumetric efficiency, lower vibration, lower noise, higher reliability and a lower heat of compression. As a result of these mechanical efficiencies, the two-stage airend can produce more air, which in turn can lead to a lower kW compressor being used to supply your air requirements. With power costs being the greatest cost factor when buying a compressor, this can lead to a significant saving over the life of your air compressor. The standard airend found in most compressors must compress the atmospheric air up to the final discharge pressure in a single-stage and requires more energy and generates more heat.

HOW THE TWO-STAGE AIRENDS WORK


Energy saving features: ¸ Highest IPM motor efficiency, even outperforming IE3 efficiency levels ¸ Superior Inovance Vector VSD control technology for main & fan motor ¸ Energy Saving Controller ¸ Direct-Drive system avoids power losses from belts ¸ Two-Stage low RPM, high efficiency airend Tidy Rigid Steel and Leak Resistant Pipework

Energy Saving Controller • Operation screen readings for Pressure/Temperature/ Power/Frequency/Run hours/ Compressor status • Day time scheduling Start /Finish • Master slave operation • Stop/start remote • Service intervals/Alarm with service provider contact details • Date and Time • Digital graphs showing usage data (wave form data) • Total KW per hour usage reading • Operating temperatures-20℃~+60℃ • Fault diagnostic read out with problem solving diagnostics • Fault History • Monitoring alarms • Supports MODBUS RTU protocol

Seamless Steel & Leak Resistant • A high-flow, leak-proof design • Rigid steel piping (with high-flow characteristics) • Eliminates oil pressure losses and the risk of rupture or oil loss through the normal ageing of traditional flexible, rubber hoses.

Inovance Inverter (VSD) The Inovance inverter has a massive 30-100% variable range which converts AC to DC to control the new IPM motor. According to your air consumption the inverter will automatically adjust the IPM motor to suite your air demand while keeping a stable pressure of 0.1bar.

Westair BSC – TWO-STAGE High Efficiency Compressor


All Westair BSC compressors are covered by a generous 5 year warranty. So confident are we

in our two-stage airend and full compressor reliability, Westair will warranty it for a full

five years! Terms and conditions apply.

EXTENDED 5 YEAR WARRANTY

Super Quiet Noise Levels – Reduced by up to 6dB(A) The large two-stage airend and quality acoustic cabinet result in exceptionally low noise levels. The new model is now one of the quietest rotary screw compressors in it’s class. The Work Health and Safety Code of Practice for managing noise at work, states that 85dB(A) is an acceptable noise level for 8 hours continuous exposure. The BSC two stage range is therefore super quiet and perfect for maintaining a safe workplace.

BSC is one of the world’s largest manufacturer of rotary screw airends (single/2 stage). They supply their airends to over 500 compressor manufacturers globally. Due to their quality and reliability, Westair/BSC will warrant any airend for its lifetime cycle. Terms and conditions apply.

High Ambient Running The BSC range has been engineered to perform in even the toughest climates. With an ambient rating of up to 45-50 Degrees Celcius, the range exceeds the temperature rating of many fixed speed compressors.
