Introducing the UNIMAC ACM-250s Quiet Air series twin-cylinder Air Compressor! This is a trade quality 2-Cylinder unit ideal for anyone looking for the performance and reliability that only an oilless electric air compressor can provide. It is the ideal compressor for the home mechanic or DIY’er!


The ACM-250s has a 1.1kW twin-cylinder motor. The 2850 RPM motor is more than twice as fast as our competitors. It has fan-forced cooling and aluminium heatsinks that keep this high-performance motor running cool.


This Unimac Quiet Air Series is engineered to be just that. Whisper Vortex cooling fans, Hush Baffle air intakes, and vulcanised rubber motor mounts and rubber tyres combine to give this an Lpa of only 61 dBa — that’s nearly library quiet!


This ACM-250s Oil-Free Air Compressor is powered by a twin-cylinder 1.1kw motor which is equivalent to a total output of 1.5 HP— up to 40% more than comparable models on the market!


With a 24L tank and 210 litres per minute air displacement the tank fills quickly.

It is capable of delivering a continuous 100-litre-per-minute air supply for a huge variety of applications. 


Unlike petrol and other belt-driven models on the market, with this oil-free electric model you don’t have to worry about engine maintenance or replacing belts or pulleys.


The quick-connect Nitto outlet lets you use a wide array of tools including grinders, impact wrenches, welders, nail guns, grease guns, chisels and more. It also has automatic on-off pressure control.


The precise easy-to-read tank pressure and line pressure gauges take the guesswork out of filling and using your air compressor.


The UNIMAC has 2 large “easy-roll” wheels with rugged airless vulcanised tyres for shop use and its extended handle makes it a breeze to move. It also has a grab handle for ease of manoeuvring in tighter spaces.

It's safe to say, the UNIMAC ACM-250s silent air compressor blows the competition away!

In addition to your statutory rights (listed on the website separately), the seller offers a 12 month warranty on all products used for private household use from the date of purchase (unless noted otherwise). The use of products for commercial purposes qualifies the purchaser to a 3 month warranty period.

Until the nature of any fault is determined, the resolution the seller can offer may vary. Where necessary, the item may need to be returned to determine fault/issue. If the products are unusable upon receiving or there is a major fault, the customer may choose between a full refund via the original payment method or a replacement product. There may be some situations that result in a reduced refund. In the case of a minor failure, the seller warranty may cover fitment of replacement parts or offer replacement parts to the customer. Other alternatives may be offered to the satisfaction of both parties.

Should you wish to claim a warranty on your item, please follow the process outlined in the Returns section.

Warranties do not apply where items are resold/rented for the purpose of profit.

You are entitled to recover reasonable postage or transportation costs if the product is confirmed to have a problem and is eligible for warranty, however, a receipt will be required.  Within 60 days of the customer purchasing the item, the seller may provide details allowing return of the item at no cost to the customer (where freight costs apply). If the product failure is found to not fall within the warranty provisions or statutory rights provided, you may be required to pay the transport and/or inspection costs (Estimates will be advised).

Prior to returning any item, our Customer Service Department must first issue you a Return Authorisation (RMA) number. All other relevant information will be sent to you at this time.

Returns are accepted in line with our warranty conditions.

Should you wish to return a faulty item, please contact us. Photos and/or videos of the item may also be requested to assist in the return process.
When a return is authorised, it is the buyer’s responsibility to ensure the product is packaged securely to prevent any damage during the return process. Failure to do so may affect the ultimate resolution to be offered.

While many spare parts are stocked in Australia, we may need to order certain parts from the supplier on your behalf. Whilst most ordered parts arrive within 15 days, a small number of difficult to order parts may require up to 8 weeks to arrive.
