Ancillary Components

The range of ancillary products offered by Marshall Brewson are used to provide the perfect solution to your compressed air requirements,  automotive, industrial, food industry, dental air, medical, breathing air or whatever ever industry or application. Marshall Brewson can offer a complete turnkey system package or point of use treatment to suit your requirements.

Inline filtration, refrigerant dryers, air storage receivers, oil/water separators, desiccant dryers, electronic condensate drains, pipework & energy efficient compressor controllers enable Marshall Brewson to offer a perfect solution to your compressed air requirements.

Marshall Brewson can supply compressed air to all ISO8573-1:2010 standards even class zero.

Why treat compressed air?
Even with an oil free compressor  the compressed air needs to be treated, the atmospheric air drawn into a compressor is a mixture of Gases, Atmospheric dirt, Micro-organisms, oil vapours, Contaminants & water vapour.  As the temperature increases in the compression process the air’s ability to carry moisture increases. When the air is cooled the excess moisture that is no longer carried is called condensate. This condensate & contaminated air need to be treated to prevent any problems downstream of the compressor house. 

ISO8573-1:2010
ISO8573 is the group of international standards relating to the quality of compressed air. The standard has nine separate parts, part 1 specifies the quality requirements of the compressed air. Parts 2-9 specify the testing methods. The ISO8573-1 give 3 separate numbers for the air quality,

1.x.x The 1st number refers to the purity class of particulates

x.1.x The 2nd number refers to the purity class of water

x.x.1 The 3rd number refers to the purity class of oil

The lower the number the higher quality of compressed air. 

Class 0 compressed air                                                                Class o does not mean zero contamination, class o requires the user & the supplier to agree contamination levels as part of a written specification. A compressor claiming to deliver class o will still need ancillary purification equipment in both the compressor room & at point of use for class 0 to be maintained.

Inline Filtration

Marshal Brewson offer the HPC/Kaeser range of high efficiency coalescing compressed air filters for the removal of water and oil aerosols, solid particulates and micro-organisms, and dust filters for the removal of dry particulate and micro-organisms from industrial compressed air systems.
Failure to remove or reduce contamination will cause a number of problems within the compressed air system. This can include corrosion within compressed air storage vessels and the air distribution system, as well as blockage or damage to production equipment; which can result in product contamination and unhealthy working conditions.

Secotec dryers

The HPC Kaeser Secotec thermal mass  dryer series  are the ultimate in energy saving dryers, these dryers save energy because the refrigerant system is shut down during breaks, periods of low demand and downtime – the control system operates without preset run-on periods. The integrated thermal mass ensures that the system is ready for operation at all times. SECOTEC dryers use flow-optimised piping so pressure losses are therefore kept to a minimum, which means that maximum system pressure can be significantly reduced. This leads to considerable savings, as each 1 bar reduction represents a 6 % decrease in power consumption and also means less air is lost through leakage. A further advantage of SECOTEC dryers is that they exceed the energy efficiency criteria required to be eligible for Enhanced Capital Allowances (ECA’s) so further savings can be made

Air Receivers

Due to its storage and buffer capacity, the air receiver plays a key role within a compressed air installation: It provides capacity during periods of peak demand and is often used to separate condensate from the compressed air. Therefore, it is important for the receiver to be correctly sized for the specific system, to be resistant against corrosion and to have long inspection intervals. Air receivers from Marshall Brewson meet all of these requirements. Our standard range of air receivers are hot-dip galvanised internally and externally and supplied with full fittings kit. All sizes, pressures & materials of air receiver can be supplied to our clients’ specification, please contact the sales team for a quotation.

Oil/Water Separators

Users who dispose of condensate by simply pouring it down the drain risk heavy fines; this is because condensate accumulated during the production of compressed air is a highly noxious mixture. The HPC Owamat Oil/Water separators are used to separate the oil from water condensate generated by the compressed air system. This is achieved by allowing the oil to rise to the top of the Owamat chamber whilst the water is passed through a series of carbon filters thus allowing the processed water into the sewage system.

Condensate Drains

Condensate is an inevitable by-product of the process of compressing air and usually contains oil & dirt. If not reliably drained off at all collection points, it can cause operational disruption and severely damage the compressed air system through corrosion. Most conventional float drains are beset with problems; the timer drains are inefficient due to compressed air wastage if no condensate is formed. The HPC Ecodrain is an electronic drain with a built in sensor that only drains of condensate not valuable compressed air. The drain can handle dirt & oil without blocking.
