Start with the part number
The part number on the old filter's label is the fastest route to a quote. A size, a faded label or a photo works too.
About Courtney Industrial Supply
A small supply business that does the legwork.
Courtney Industrial Supply is an owner-operated supplier of dust collector filters and parts, run by Alex Courtney in Sycamore, Illinois. You send part numbers or sizes; we find the right filters, quote them clearly, and have them shipped straight to you from the manufacturer or distributor.
How the business works
No warehouse, no catalog maze.
Most filter changeouts start with something already known: the part number on the old filter's label, a size from the last order, or the collector's manual. That is where we start too.
We source each request from manufacturers and distributors, send you a written quote, and once you approve it, the order ships directly from the source to your dock. Without a warehouse in the middle there is no extra handling step.
Courtney Industrial Supply is a new business. Every request is handled by Alex Courtney, the owner, so you deal with one person who knows your request from the first email to delivery.
Based in Sycamore, Illinois, serving plants across Northern Illinois and Southern Wisconsin.
How we work
A straightforward buying experience
The aim is simple: make a replacement-part request easy to send and easy to quote, without making the buyer navigate a giant catalog first.
Make unknowns acceptable
A buyer should not be blocked because a technical detail is missing. We identify the gaps that matter and ask about them.
Quote plainly
Price, lead time and any alternates are spelled out on the quote, so it is easy to compare and approve.
Only claim what is true
No invented stock, partnerships or reviews. If a part cannot be found or a date cannot be met, we say so.
Scope
Dust collector filters, one request at a time.
We quote filter bags, pleated cartridges, cages and venturis, pulse valves and diaphragm kits, and the gaskets and hardware that go with them. Other parts with a manufacturer and part number are welcome too; we will tell you honestly whether they are a fit.
