Frequently Asked Questions

Is the 42445 air filter compatible with my Sullair compressor?

The 42445 air filter is designed for Sullair air compressors that require this exact air intake filter element. Compatibility should always be confirmed by matching 42445 in your parts manual or by verifying your compressor model and serial number before ordering. Not sure? Reach out with your compressor model and serial number and we’ll help confirm compatibility. 

What does the 42445 air filter do?

The 42445 is an intake air filter element that removes dust, dirt, and airborne contaminants before air enters the compressor. This helps protect internal compressor components and maintain proper airflow and efficiency.

How often should the 42445 air filter be replaced?

Air filters should generally be replaced around every 2,000 hours of operation, though this interval may be shorter in dusty or dirty environments. Regular replacement helps maintain airflow and protects the compressor from contamination.

Is this an OEM part?

This is an OEM-equivalent replacement filter built to meet or exceed the performance of the original air filter while offering a cost-effective alternative. 

Why is it important to replace my air filter?

The intake air filter helps prevent dust, dirt, and airborne particulates from entering the compressor. A clean air filter supports proper airflow into the machine, while a dirty or restricted element can reduce intake efficiency and contribute to unnecessary wear on internal components. Keeping the air filter in good condition is a basic but important part of preventative maintenance.  

How difficult is it to install?

Air filter replacement is generally considered a routine maintenance item. In most applications, the old filter element is removed from the intake housing and the new filter is installed in its place. The exact procedure can vary depending on the compressor model, so installation should always be performed with the machine shut down, isolated, and depressurized, while following the equipment’s service instructions. 

Do you carry other parts for Sullair compressors?

Absolutely. We stock air filters, oil filters, separators, lubricants, and other maintenance parts for Sullair compressors. If you don’t see what you need, just ask and we’ll help you find it.

How do I know which oil to use in my Sullair compressor?

Stationary rotary screw compressors may have specific oil requirements that differ from reciprocating or portable units. To make sure you’re using the right lubricant for your machine, check out our full guide here: Choosing the Right Oil for your Sullair Compressor. It covers the recommended options for rotary screw compressors and helps you match your compressor with the proper oil.
