Quick answer
Compressor and generator finance helps tradies buy air and power equipment and repay from the work it makes possible. The key is sizing: undersized units stall jobs, oversized ones waste money. Unsecured options typically run from $5k to $500k, property-secured from $20k to $5m, for business use only, with no credit check on first enquiry.
Key points
- Size the unit to the tools and the number of people using it
- Generators and compressors have very different duty and noise profiles
- Fuel, servicing and transport are ongoing costs
- A failed unit stops every tool that depends on it
- No credit check when you first enquire
Nobody brags about their compressor, but plenty of jobs stop without one. Nail guns, impact wrenches, sandblasters, spray gear and a long list of pneumatic tools all rely on air. Out on a new estate with no power connected, the generator is what runs the lights, the chargers and the saw. When either fails, the crew stands around and the clock keeps running.
How do I size a compressor or a generator?
Sizing mistakes are expensive in both directions. An undersized machine struggles, overheats and shortens its own life. An oversized one costs more to buy, move and fuel.
For a compressor, the basics are:
- list the air tools that run at once, with their air requirements
- add headroom so the unit is not at its limit all day
- decide between a portable, a trailer-mounted and a fixed workshop unit
- consider electric versus engine drive, depending on whether power is available
For a generator:
- list the loads you will run together, including starting surges for motors
- decide whether you need clean power for electronics
- think about noise, since some sites and neighbourhoods have limits
- plan for fuel capacity so it lasts a working day
Ask the supplier to size from your actual tool list rather than a general guide.
Compressor or generator: what separates them?
| Feature | Compressor | Generator |
|---|---|---|
| Output | Compressed air | Electrical power |
| Typical users | Carpenters, mechanics, sprayers, blasters | Everyone on sites without power |
| Key spec | Air delivery and pressure | Continuous output and surge capacity |
| Common issue | Moisture, oil and filter care | Fuel quality and overload |
| Transport | Wheeled or trailer-mounted | Frame-mounted or trailer-mounted |
Some workshops run both, and some engine-driven welders double as generators, which is covered on our welding equipment page.
How do lenders look at these purchases?
Compressors and generators are mid-range assets: not as tracked or resellable as earthmoving plant, but not trivial like a drill. Lenders usually want to see:
- a written quote with make, model and capacity
- whether the unit is new, demonstrator or used
- how the business will use it and what it earns
- your recent business bank statements
- any deposit or security that supports the amount
Smaller units can fit a working-capital loan, while trailer-mounted or industrial setups may justify an asset-linked structure. Property-secured loans from $20k to $5m exist for bigger purchases.
What does ownership really cost?
| Ongoing cost | Notes |
|---|---|
| Fuel | Engine-driven units burn it by the hour |
| Servicing | Oil, filters, belts, spark plugs, valves |
| Consumables | Air hoses, fittings, dryers, extension leads |
| Storage and security | Stolen generators are a regular problem |
| Transport | Trailers, tie-down points, vehicle capacity |
A theft is a particular risk with generators because they are easy to sell. Ask your insurer what is required to be covered on site and overnight. The equipment payback calculator is a quick way to compare ownership against hiring power on big jobs.

An illustrative example
This is a made-up scenario for explanation only.
A small carpentry and decking business has been running tools from a single portable generator and paying a mate to lend a compressor for framing. The generator is too small to run two saws and the lights at once, and the borrowed compressor is not always available. The owner buys a trailer-mounted compressor and a larger inverter generator and finances them together.
The change is practical: framing starts on time, two people can work at once and the owner no longer turns down jobs that need air. The owner checks that the extra jobs would cover the repayments and that the trailer can be towed legally.
When does a trailer-mounted setup make sense?
If you move between sites daily, or you share a unit between crew, a trailer-mounted compressor or generator saves loading and unloading. It also needs a tow vehicle, secure parking and a place to chain it. The trailer finance page covers the trailer side, and power tool finance is relevant if your kit includes cordless platforms.
Where else is this equipment used?
Compressors and generators are cross-trade, but they show up especially in concreting, where vibrators, saws and finishing tools need reliable power. The concrete equipment finance page looks at how the pieces fit together on a pour.
How can I reduce downtime on air and power gear?
Basic maintenance prevents most failures. Drain the compressor tank after use to clear moisture, change filters and oil on schedule and keep hoses off the ground where they get run over. For generators, use fresh fuel, run the unit periodically if it sits, and keep the air filter clean. Carry spare spark plugs, fuses, fittings and a spare hose. For the cost of a few spares, a failure at seven in the morning becomes a ten-minute fix instead of a lost day. Logging service dates on your phone also helps if you ever sell the machine, because a documented history lifts the price.

Frequently asked questions
How do I size a compressor?
Add up the air demand of the tools that run at the same time, then allow headroom. Your supplier can match the specification to your tool list, which is better than guessing from a brochure.
What is the difference between an inverter and a conventional generator?
Inverter generators produce cleaner power and tend to be quieter, which suits sensitive electronics. Conventional units can be cheaper per unit of output. The choice depends on what you power.
Do I need a generator if I have a battery tool platform?
Many tradies still carry one for charging, lighting and corded tools on sites without power. The size depends on how much you run at once.
Is it smarter to buy a trailer-mounted unit?
For larger jobs, yes, since it moves with you and can serve a crew. Smaller units are easier to carry but limit what you can run.
Can I finance second-hand units?
Often, with a service record and a seller who can be identified. Engine hours and maintenance history matter for both types.
