SIP DD 2hp 50ltr Low Noise Oil-Free Compressor

Enjoy powerful, whisper-quiet compressed air with the SIP DD 2hp 50ltr Low Noise Oil-Free Compressor (Product Code: 05479). Engineered for workshops, garages and trade environments where noise matters, this direct drive compressor operates at just 62dB – roughly the volume of a normal conversation – so you can work without hearing protection and without disturbing others nearby.

At the heart of the unit is a latest-generation 2-pole, 2hp (1.5kW) motor paired with a twin-cylinder pump that delivers 9.6CFM piston displacement and 4.7CFM Free Air Delivery (FAD). This gives you a consistent, dependable air supply for a wide range of everyday tasks including tyre inflation, brad nailing, stapling, airbrushing and spray painting.

The generous 50-litre receiver tank stores air at up to 8 bar (116 psi) maximum pressure, reducing the frequency of motor cycling and ensuring a smooth, uninterrupted air flow. Twin pressure gauges – one for tank pressure and one for working pressure – let you monitor output at a glance, while the built-in regulator and quick-release connectors make it easy to dial in the exact pressure your tools require.

Because this compressor is oil-free, there are no oil changes to worry about and no risk of oil contamination reaching your tools or finished work – making it the ideal choice for clean-air applications such as airbrushing, dental work and food-grade environments. Simply plug into a standard 230V (13A) domestic socket and you’re ready to go.

Key Benefits

• Ultra-Quiet 62dB Operation – Work in comfort without ear defenders. At just 62dB, this is one of the quietest compressors in its class – perfect for indoor workshops, home garages and noise-sensitive environments.
• Oil-Free, Low Maintenance Design – No oil top-ups, no oil changes, no contamination risk. Spend less time on maintenance and more time on the job, with cleaner air delivered to your tools.
• Powerful 2hp Direct Drive Motor – The latest-generation 2-pole motor delivers reliable, efficient performance without the belts, pulleys and additional servicing of belt-drive alternatives.
• 4.7CFM Free Air Delivery – Enough airflow for inflation, nailing, stapling and airbrushing. The 9.6CFM piston displacement ensures efficient air intake for sustained use.
• 50-Litre Receiver Tank – A large tank capacity means longer run times between motor cycles, reducing wear and maintaining consistent pressure for uninterrupted work.
• Plug-and-Play 230V Convenience – Runs from a standard 13A domestic socket – no special wiring or three-phase supply needed.

Why Choose the SIP DD 2hp 50ltr Low Noise Oil-Free Compressor?

If you need a compressor that balances performance, low noise and minimal upkeep, the SIP 05479 is a standout choice. Its oil-free design eliminates routine oil servicing and delivers clean, dry air that won’t damage precision tools or contaminate finishes. The 62dB noise rating puts it well below the 85dB threshold at which hearing protection becomes a legal requirement in the workplace, making it a practical solution for shared spaces and long working days.

Backed by the SIP brand – a trusted name in workshop equipment across the UK – this compressor combines a robust build quality with a user-friendly package that’s ready to work straight from the box.

Q: How loud is the SIP DD 2hp 50ltr compressor?

A: The SIP DD 2hp 50ltr compressor operates at just 62dB, which is comparable to a normal conversation. This makes it one of the quietest compressors in its class and suitable for indoor use without hearing protection.

Q: Does an oil-free compressor need maintenance?

A: Oil-free compressors require significantly less maintenance than lubricated models. There are no oil levels to check or oil changes to schedule. Routine care is limited to draining the tank of condensation, checking fittings and keeping the air intake filter clean.

Q: What can I use a 4.7CFM compressor for?

A: A 4.7CFM Free Air Delivery is sufficient for tyre inflation, brad nailing, stapling, airbrushing and light spray painting. For continuous high-demand tools such as large spray guns or impact wrenches, a higher CFM output may be required.

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

A: Yes. The SIP DD 2hp compressor runs on a standard 230V, 13A domestic supply. No special wiring or three-phase power is needed.

Q: What is the difference between piston displacement and FAD?

A: Piston displacement (9.6CFM) is the theoretical volume of air moved by the pistons. Free Air Delivery or FAD (4.7CFM) is the actual usable air output after accounting for system losses. FAD is the figure you should use when matching a compressor to your air tools.
