Air Preparation and Treatment
A top quality compressed air system, providing clean, dry and occasionally sterile air, working at optimum energy efficiency to power your pneumatic air tools and control gear is a wonderful thing. If used untreated, atmospheric air bearing large amounts of water and other contaminants will be introduced into your system. To avoid considerable damage to your equipment, unnecessary maintenance costs, risk of product spoilage and other costly downtime, you must protect your air supply from contamination. This can be achieved by using the right air preparation and treatment equipment.
As an approved distributor for both Gardner Denver and Parker Hannifin, our engineering teams have industry leading air preparation and treatment ranges available to provide you with the clean, dry air supply you need. A system fitted with the appropriate air treatment equipment in place with provide you with many years of trouble free performance and optimise energy consumption.
Harrier provide a range of compressed air dryers from a number of manufacturers including Gardner Denver CompAir, and Parker Hannifin. With experience of providing clean air solutions across a wide range of industry applications, the harrier engineering team will be very happy to discuss your needs and recommend the appropriate solutions available.
Refrigerant Air Dryers
Refrigerant dryers are a proven air treatment technology, proven in thousands of applications. Characterised by energy efficiency, and modest running costs, these dryers will remove water from your air supply, providing clean and dry general purpose air suitable for many industry applications.
Dessicant Air Dryers
Dessicant, or Adsorption compressed air dryers remove moisture by passing air over a regenerative desiccant material, which attracts and retains water vapour molecules. The term pressure dew point refers to the temperature at which water condensation will occur, a typical pressure dew point specified for an adsorption dryer is -40°C which prevents corrosion and inhibits the growth of micro-organisms. This delivers a high quality air supply, suitable for more sensitive and specialised applications.
Harrier’s team are well versed in assessing the required filtering, and supply a wide range of air treatment filters that will efficiently remove oil, water and other dirt particles, delivering only clean, dry air at the point of use.

Coalescent filters remove very fine liquid droplets from the gas stream and convert them into large droplets of liquid which can then be easily drained from the system. This process of “coalescing” the small droplets into larger ones gives the filters their name.
Filters in the Parker range coalesce liquid droplets efficiently and indefinitely without loss of efficiency or flow capacity. This is achieved by the liquid draining as rapidly as it is collected.
There are two important aspects to consider when selecting and installing a coalescing filter:
1. It is imperative that you use a filter with the right capacity to handle the maximum flow rate
2. Automatic drains must always be installed with coalescing filters. This helps to avoid liquid carryover.
Harrier Pneumatics supply replacement filter elements for Domnick Hunter, Hankison, Ultrafilter, Worthington and Ingersoll Rand air filters, and many other manufacturers also.
Water vapour is removed by the principle of selective permeation through a membrane. The membrane module consists of hollow membrane fibres each permeable to water vapour only. As compressed air passes through the centre of these fibres water vapour permeates the walls of the fibre and dry air exits from the other end of the fibre. Moisture laden air is carried away and dry air piped to the application.
Oil and Odour Removal
Air and Oil separators are essential to smooth operation, as oil in the cooling medium will reduce the efficiency of your compressed air system. Oil on the surface of a heat exchanger degrades heat conductivity—this will push up operating costs. Efficient filtering will contribute to improved plant cleanliness, will improve environmental performance and reduce your oil consumption.
