Product Details
Description
Keep workshop inflation, blow cleaning, second-fix nailing and light spray tasks moving without giving up valuable floor space. Part of the JCB Silent Pro range, the JCB-OFAC-50V combines 300L/min (11CFM) air displacement with a 50L vertical steel receiver, a twin-cylinder oil-free pump driven by a 1500W (2HP) 4-pole low-speed brushless motor, up to 8 bar pressure and a regulated Euro outlet for compatible air tools and accessories.
The upright wheeled layout is built for garages, service bays, fit-out work and maintenance teams that need useful stored-air capacity in a compact footprint. Twin pressure gauges show receiver and regulated outlet pressure, while automatic pressure cut-off, integrated cooling fans and a stainless-steel braided pump-to-tank hose support controlled operation. Always match the connected tool to the airflow, pressure and duty-cycle figures in the specification table.
Silent Pro Workshop Air
Silent Pro is JCB's noise-focused compressor sub-brand for indoor workshop duties. The JCB-OFAC-50V combines that range positioning with a manual-rated sound power level of 86dB(A) LwA and 3dB(A) uncertainty, giving garages and workshops a confirmed figure for planning use alongside task-specific PPE.
Twin-Cylinder Brushless Performance
A 4-pole low-speed brushless motor drives the twin-cylinder oil-free pump at 1450rpm to deliver 300L/min (11CFM) displacement. The brushless construction removes carbon-brush replacement from routine motor maintenance, while the twin-cylinder arrangement delivers the confirmed intake capacity for compatible workshop air tasks.
50L Air, Smaller Footprint
The durable 50L steel receiver stores compressed air for intermittent workshop tasks and can reduce motor cycling compared with a smaller receiver when air demand is intermittent. The vertical layout keeps the footprint to 440 x 740mm, making it practical where floor space must stay clear for workbenches, vehicles and material handling.
Controlled, Cooled and Lower Maintenance
Automatic pressure cut-off stops receiver charging at the set maximum pressure, while integrated cooling fans help manage operating temperature. The oil-free direct-drive pump removes routine pump-oil changes, the stainless-steel braided pump-to-tank hose provides a robust air-transfer connection and the fitted condensate drain valve supports routine receiver care.
Who Is This For?
- Vehicle workshops and garages carrying out tyre inflation, blow cleaning and routine service work.
- Joiners and fit-out contractors using compatible pneumatic nailers and staplers for intermittent fixing tasks.
- Facilities and maintenance teams that need a movable compressed-air source for workshop duties.
- Finishing and fabrication areas using compatible airbrush or light spray equipment with suitable ventilation and filtration.
- Trade workshops that need 50L stored-air capacity without committing as much floor space to a horizontal receiver.
Safe Use
- For indoor use only. Keep the compressor dry and use an RCD-protected supply where required.
- Wear suitable eye and hearing protection. Never direct compressed air at people or clean clothing while it is being worn.
- Check every connected tool's working pressure, airflow and duty-cycle requirements before use.
- Do not use the compressor to supply breathing air.
- Drain condensate and inspect the receiver as directed in the supplied manual. Do not modify or repair the receiver.

Frequently Asked Questions
Is a 50L air compressor big enough for workshop tools?
A 50L receiver, 2HP motor, 300L/min air displacement and 8 bar maximum pressure suit many intermittent workshop tasks. Check the connected tool's airflow and duty-cycle requirements against the specification table before use.
What jobs can the JCB-OFAC-50V handle?
Its 300L/min (11CFM) displacement is suited to compatible inflation, blow cleaning, pneumatic nailing and stapling, airbrushing and light spray tasks. Tool suitability depends on required pressure, delivered airflow and run time.
Does this oil-free air compressor need pump-oil changes?
No. The direct-drive pump is oil-free, so there is no routine pump-oil change. The receiver must still be drained and inspected as stated in the manual.
What does Silent Pro mean on the JCB-OFAC-50V?
Silent Pro is the JCB noise-focused compressor sub-brand. This model carries a confirmed sound power level of 86dB(A) LwA with 3dB(A) uncertainty. LwA is a sound-power rating and should only be compared with other LwA figures.
What motor and pump system does it use?
A 1500W (2HP) 4-pole low-speed brushless motor drives a twin-cylinder oil-free pump at 1450rpm. Integrated cooling fans help manage operating temperature, and automatic pressure cut-off stops receiver charging at the set cut-off pressure.
How much workshop floor space does the vertical compressor use?
The assembled dimensions are 710 x 440 x 740mm (H x W x L), giving a 440 x 740mm footprint with the 50L receiver arranged vertically.
Can I regulate the outlet pressure?
Yes. Twin gauges show tank and working pressure, and the regulator sets the outlet pressure up to the 8 bar maximum for a compatible tool.
What electrical supply does it use?
The compressor is rated at 230V and 1500W, with a 1.5m power cable. Use a suitable indoor supply and follow the manual's electrical safety instructions.
How does the automatic pressure cut-off work?
The automatic cut-off stops receiver charging when the set maximum pressure is reached. This prevents the motor from continuing to run once the 50L receiver has reached its operating pressure.
Can the compressed air be used for breathing?
No. This compressor does not supply breathing-quality air and must not be used for respiratory equipment without a separately engineered and approved treatment system.
