Air Receivers and Dryers
Compressed air leaves the compressor hot, wet and pulsing, and feeding it straight to tools and valves shortens the life of everything downstream. Air receivers store and steady the supply so the compressor cycles sensibly, and let the air cool so water drops out where it can be drained. Dryers then take the dewpoint down: refrigerant units to around +3°C for general plant air, desiccant units to -40°C or lower where lines run outdoors or the process specifies an ISO 8573-1 water class. Machinery Masters lists receivers, dryers and filtration from verified sellers, from point-of-use units to plant room installations, with direct seller contact on every listing.

Air Receivers and Dryers Product Types
Treatment equipment divides by what it removes from the air and how dry the result has to be. These are the machine types the category holds.
Vertical and horizontal air receivers
Pressure vessels from a few hundred to several thousand litres that buffer demand peaks and condense water out of hot compressed air. The data plate, test pressure and examination paperwork are as important as the shell.
Refrigerant compressed air dryers
Dryers that chill the air to condense moisture, delivering a pressure dewpoint of around +3°C. The economical choice for indoor plant air, sized by flow at working pressure rather than by compressor kilowatts.
Desiccant compressed air dryers
Twin-tower and modular units, such as the Pneudri type, that adsorb moisture to dewpoints of -40°C and below. Specified where airlines run outside, freeze risk exists or the process demands very dry air.
Filtration and condensate management
Coalescing and particulate filter sets, automatic drains and oil-water separators that bring air to its ISO 8573-1 class and dispose of condensate legally. Cheap components that protect expensive ones.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
Air treatment pays for itself wherever wet or dirty air would damage product, tooling or pipework. These settings generate most of the demand.
Spray and finishing shops
Paint and powder finishes fail visibly when water or oil reaches the gun, so finishing lines run dryers and coalescing filtration as standard. Dewpoint, not pressure, is the specification that matters here.
Pneumatic controls and instrumentation
Control valves, positioners and instruments on process plant demand dry, filtered air because moisture corrodes small internals and freezes in winter. Desiccant drying is the norm for instrument air.
Outdoor and cold-exposed airlines
Yards, loading bays and external pipe runs freeze at the lowest point of the line, stopping tools and valves. Drying the air below the coldest expected temperature removes the problem at source.
Plant room upgrades
Adding or resizing a receiver smooths demand peaks, reduces compressor cycling and cuts energy cost. It is often the cheapest single improvement available to an existing air system.
Benefits from Machinery Masters
Treatment equipment is usually bought to fix a specific problem, and the marketplace shortens the path from problem to installed fix.
01
Treatment alongside the generation
Receivers and dryers sit in the same category tree as the compressors they serve, so an air quality upgrade and a compressor replacement can be sourced in the same search.
02
Pressure equipment with its paperwork
Direct seller contact means data plates, test certificates and examination history can be requested and checked before purchase, which matters more on pressure vessels than on most plant.
03
Sized against stated specifications
Flow ratings, dewpoints and vessel volumes are comparable across listings from different sellers, so matching a dryer to your compressor's output is a desk exercise rather than guesswork.
Frequently Asked Questions About Air Receivers and Dryers
A refrigerant dryer reaching a +3°C pressure dewpoint covers most indoor plant air at the lowest running cost. Choose desiccant drying where airlines run outdoors or near freezing, or where the process specifies a dewpoint of -40°C or below, and budget for the purge air desiccant towers consume. Check your coldest exposed pipe run before deciding.
A common rule of thumb is six to ten litres of receiver volume per cfm of compressor free air delivery, with more where demand comes in heavy bursts. An undersized receiver makes the compressor cycle rapidly, which wastes energy and wears the machine. Confirm the vessel's rated pressure exceeds your compressor's maximum before buying.
In the UK, air receivers in service fall under the Pressure Systems Safety Regulations 2000: you need a written scheme of examination and periodic inspection by a competent person. The vessel must carry a legible data plate with design pressure and test details. Ask the seller for the plate photograph and any examination reports before committing.
On a refrigerant dryer, confirm the refrigerant type is still serviceable under F-gas rules and that the dewpoint indicator reads correctly under load. On a desiccant unit, ask when the desiccant was last changed and listen for the tower changeover valves cycling cleanly. Service records and a run under load settle most doubts.
Yes. Standalone dryers install in the line after the receiver, where the air is coolest and the dryer works least. Match the dryer's rated flow at your working pressure to the compressor's free air delivery with a margin of around twenty percent. Tell the seller your compressor's FAD and pressure and they can confirm the match.
