Choose an MGF PRIME Compressor Without Integrated Drying

The PRIME family is MGF's higher-capacity oil-free platform, covering compact single-pump units through tandem and multi-pump systems for heavier demand. The products below are the no-dryer configurations currently listed on this Tanair range page.

MGF separates PRIME into standard open versions and acoustically enclosed CS versions. If your application requires an integrated membrane or adsorption dryer, use the dedicated dryer ranges rather than adding a no-dryer model by assumption.

Selection note: size the compressor around the required free air delivery at the actual working pressure, simultaneous equipment demand and duty cycle. Oil-free compression does not by itself establish the final air-quality specification at point of use.

Which PRIME Configuration Suits the Installation?

Open PRIME SReceiver-mounted oil-free compressors for plant rooms and installations where acoustic enclosure and integrated drying are not required.
Tandem & Multi-PumpHigher-output PRIME systems use multiple compressor pumps to support greater simultaneous demand and larger installations.
CS Silenced PRIMEAcoustically enclosed models reduce operating noise where the compressor location is closer to occupied areas.

Important: MGF has revised parts of the larger PRIME family over time, including HD configurations and performance ratings at different working pressures. Always confirm the exact current specification for the selected model rather than comparing headline CFM values measured at different pressures.

What to Check Before Ordering

Required FADUse free air delivery at the pressure your equipment actually needs, allowing for simultaneous demand and sensible reserve capacity.
Working PressureConfirm the pressure required after pipework and treatment losses. MGF PRIME variants differ by model and configuration.
Duty & Operating PatternCheck expected run time, peak demand and whether duty-sharing or additional standby capacity is required.
Air TreatmentThese models do not include an integrated dryer. Specify separate drying and filtration where the application requires controlled moisture or a defined air-quality class.
Electrical SupplyThe range includes single-phase and three-phase options. Confirm the available supply before selecting the exact machine.
Noise & LocationChoose an acoustically enclosed CS model where noise control is important, while maintaining suitable ventilation and service access.

MGF PRIME Without Dryer FAQs

Are these MGF PRIME compressors oil-free?

Yes. The PRIME family shown here uses oil-free compression, so compressor lubricant is not introduced into the compression process.

Do these models include an air dryer?

No. This page is specifically for PRIME configurations without an integrated dryer. MGF also offers separate PRIME ranges with membrane and adsorption drying.

What is the difference between open and CS versions?

Open PRIME models use a conventional exposed compressor arrangement, while CS versions place the compressor in an acoustic cabinet to reduce operating noise.

Can I size a compressor from CFM alone?

No. Compare free air delivery at the required working pressure and consider simultaneous demand, duty cycle, reserve capacity and treatment losses.

Does oil-free mean the complete system automatically meets a dental or medical air standard?

No. Final air quality depends on the full installation, including drying, filtration, pipework, commissioning, maintenance and the specific requirements of the connected equipment.

Can Compressed Air Systems UK help size the PRIME range?

Yes. Send us the equipment being supplied, simultaneous demand, required pressure, electrical supply, operating pattern and any stated air-quality requirement.
