FAQ

A diesel air compressor is a device that converts diesel fuel energy into compressed air. It uses a diesel engine to power an air pump, which draws in atmospheric air and compresses it into a storage tank at high pressure.

The compressed air can then be used to power various tools and equipment by releasing the stored air through a hose, converting the potential energy back into kinetic energy for practical applications.

Diesel air compressors offer several advantages, including higher power output compared to electric models, making them suitable for heavy-duty applications.

They provide greater mobility since they don’t require a direct electrical connection, making them ideal for remote job sites. Diesel engines also tend to have longer lifespans and better fuel efficiency for continuous operation.

Regular maintenance frequency depends on usage intensity, but a general schedule includes:

Daily: Checking oil levels, air filter condition, and for any leaks or unusual noises.

Weekly: Inspecting hoses and connections for wear, checking belt tension, and draining moisture from the air tank.

Monthly: Changing the oil filter and checking spark plugs (if applicable).

Annually: Comprehensive service including valve inspection, piston ring check, and overall system performance evaluation.

Heavy-use environments may require more frequent maintenance intervals.

CFM stands for Cubic Feet per Minute, a measurement of the volume of air a compressor can deliver at a specific pressure level.

It’s crucial because it determines what tools and equipment the compressor can effectively operate. Each pneumatic tool has a CFM requirement, and choosing a compressor with insufficient CFM will result in poor tool performance or inability to operate multiple tools simultaneously.

PSI (Pounds per Square Inch) measures the pressure at which air is delivered from the compressor.

Different tools require different PSI levels to operate effectively. While most tools work at 90-100 PSI, some heavy-duty equipment may require higher pressure. A compressor’s PSI rating indicates its maximum pressure capability, which affects both tool compatibility and the rate at which the tank refills.

Tank size selection depends on your application needs. Larger tanks (100+ gallons) are better for continuous use with tools that consume high volumes of air, as they provide a reserve that reduces the frequency of the compressor cycling on and off.

Smaller tanks (20-60 gallons) are more portable and sufficient for intermittent use with lighter tools. Consider both your mobility needs and the air consumption patterns of your equipment when selecting a tank size.

If your diesel compressor won’t start, check these common issues:

1. Ensure there’s sufficient diesel fuel in the tank

2. Check the battery charge and connections

3. Inspect the fuel filter for clogs

4. Verify the oil level (many models have low-oil shutoff)

5. Check for a tripped circuit breaker or blown fuse

If these checks don’t resolve the issue, contact technical support for further diagnosis.

Rapid pressure loss typically indicates a leak in the system. Check all hose connections, fittings, and the tank itself for signs of air leakage.

Other possible causes include a faulty pressure relief valve, worn piston rings, or a damaged check valve. Inspect the pressure gauge to see if the compressor is cycling properly and maintaining pressure when not in use.

Overheating can be caused by several factors: insufficient oil levels, a dirty or clogged oil cooler, blocked air intake, or operating the compressor in extremely high ambient temperatures.

It can also result from overloading the compressor beyond its capacity or a malfunctioning thermostat. If your compressor consistently overheats, shut it down immediately to prevent damage and have it inspected by a professional.

Our standard warranty covers manufacturing defects in materials and workmanship for 2 years from the date of purchase. This includes the diesel engine, compressor pump, and major components.

The warranty does not cover damage from improper use, lack of maintenance, accidents, or normal wear items such as filters, hoses, and gaskets. Extended warranty options are available for additional coverage.

Service is available through our network of authorized service centers located in major cities worldwide. You can find the nearest service center using the locator tool on our website.

We also offer mobile service units in select regions for on-site repairs. For remote locations, our technical support team can guide you through basic troubleshooting and arrange for parts delivery.

Most common replacement parts are available for same-day or next-day shipping from our regional distribution centers. Specialized components typically ship within 2-3 business days.

For emergency situations, we offer expedited shipping options. We recommend maintaining a stock of critical wear parts for your specific model to minimize downtime during unexpected failures.
