SIP DD 3hp 50ltr Low Noise Oil-Free Compressor

Step up to greater airflow without sacrificing workshop comfort. The SIP DD 3hp 50ltr Low Noise Oil-Free Compressor (Product Code: 05480) pairs a powerful 3hp motor with a low-noise twin-cylinder pump to deliver 9CFM Free Air Delivery at just 71dB – keeping noise well below the 85dB level at which hearing protection becomes a legal workplace requirement.

Powered by a latest-generation 2-pole, 3hp (2.2kW) motor, this direct drive compressor produces a 13.6CFM piston displacement that translates into a genuine 9CFM FAD – nearly double the usable output of many 2hp models. That extra capacity makes it a confident choice for more demanding tasks such as continuous nailing, heavier stapling, spray painting and operating multiple air tools in sequence.

The 50-litre receiver tank stores compressed air at up to 8 bar (116 psi) maximum pressure, providing a generous reserve that reduces motor cycling and maintains a smooth, consistent supply. Dual pressure gauges – for tank and working pressure – give you instant visibility, while the integrated regulator and quick-release connectors let you fine-tune output to match your tools precisely.

As an oil-free compressor, there are no oil changes, no oil-level checks and no risk of lubricant contaminating your air supply. This means cleaner air reaching your tools and finishes – essential for airbrushing, detailing work and any application where air purity matters. The unit runs from a standard 230V (13A) domestic socket, so there’s no need for specialist wiring or three-phase power.

Key Benefits

• High-Output 9CFM Free Air Delivery – Nearly double the FAD of smaller models, giving you the airflow to tackle continuous nailing, stapling and spray work without waiting for the tank to recover.
• Low Noise 71dB Operation – Comfortably below the 85dB threshold for mandatory hearing protection, making this compressor suitable for indoor workshops, shared spaces and extended working sessions.
• Oil-Free, Low Maintenance Design – No oil top-ups, no scheduled oil changes and no contamination risk. Enjoy cleaner air to your tools and equipment with minimal ongoing upkeep.
• Powerful 3hp Direct Drive Motor – The latest-generation 2-pole motor delivers strong, efficient performance without the belts, pulleys and additional servicing associated with belt-drive compressors.
• 50-Litre Receiver Tank at 8 Bar – A large-capacity tank reduces compressor cycling, extends component life and delivers a steady, uninterrupted air supply even during sustained use.
• Plug-and-Play 230V Convenience – Runs from any standard 13A domestic socket – no electrician required, no three-phase supply needed. Unbox, connect and start working.

Technical Specifications

Ideal Applications

With 9CFM FAD, the SIP DD 3hp 50ltr oil-free compressor handles a wider range of tasks than lower-output models:

• Tyre and inflatable inflation
• Continuous brad nailing and stapling on site
• Airbrushing and detail spray painting
• HVLP spray guns for small to medium finishing jobs
• Cleaning, dusting and blow-down tasks
• Operating pneumatic ratchets and small air tools
• Home workshops, garages and indoor trade environments
• Mobile contractors needing a single-phase, portable unit

Why Choose the SIP DD 3hp 50ltr Low Noise Oil-Free Compressor?

The SIP 05480 sits in a sweet spot between compact workshop compressors and larger industrial units. Its 3hp motor and 9CFM FAD give you significantly more airflow than entry-level machines, while the oil-free, direct drive design keeps servicing to a minimum. At 71dB it remains quiet enough for indoor use without ear defenders, yet delivers the power to run pneumatic nailers, staplers and HVLP spray equipment with confidence.

For users who have outgrown a 2hp compressor or need to run air tools with higher CFM demands, this model provides a meaningful step up in performance without requiring three-phase wiring or a dedicated compressor room. It plugs straight into a standard 13A socket and is ready to work from the moment it arrives.

Backed by the SIP brand – one of the UK’s most established names in workshop and garage equipment – the DD 3hp 50ltr compressor combines robust engineering with everyday practicality.

SIP DD 3hp vs SIP DD 2hp – Quick Comparison

Use this snippet to support category-level or comparison content:

Q: How loud is the SIP DD 3hp 50ltr compressor?

A: The SIP DD 3hp compressor operates at 71dB – roughly equivalent to a vacuum cleaner at moderate distance. This is well below the 85dB level at which hearing protection is legally required in the workplace, making it comfortable for indoor use during extended sessions.

Q: What is the difference between the SIP DD 2hp and 3hp compressors?

A: Both models share a 50-litre tank and 8 bar maximum pressure, but the 3hp (05480) delivers 9CFM FAD compared to 4.7CFM on the 2hp (05479). The 3hp model is better suited to higher-demand tools and continuous use, while the 2hp model is quieter at 62dB and lighter at 31 kg.

Q: Can I run spray guns with a 9CFM compressor?

A: Yes. A 9CFM FAD is sufficient for most HVLP spray guns used in small to medium finishing and detail work. For large-area automotive refinishing or high-volume production spraying, check your gun’s CFM requirement – some larger guns may need 12CFM or more.

Q: Does an oil-free compressor deliver clean enough air for airbrushing?

A: Oil-free compressors eliminate oil vapour from the air supply, which is a significant advantage for airbrushing and fine finishing. For the cleanest possible results, pairing the compressor with an inline moisture trap or air filter is recommended to remove any residual condensation.

Q: Can I run this compressor from a standard plug socket?

A: Yes. The SIP DD 3hp compressor draws from a standard 230V, 13A domestic supply. No specialist wiring or three-phase power is required.

Q: How heavy is the SIP DD 3hp compressor?

A: The unit weighs 38.5 kg (net), making it portable enough to move around a workshop but sturdy enough to stay in place during operation. The packaged weight is 41.3 kg.
