About Bags and Cages
Bags and Cages is the online parts store for Air Engineering Sales Corporation, an industrial dust collection and air pollution control company based in Mountaintop, Pennsylvania. Air Engineering Sales has been solving dust and material-flow problems for more than 40 years. We stock genuine Goyen valves and parts, replacement filter bags, cages, and cartridge filters, and most orders ship from stock so your collector gets back online fast.
Who’s behind Bags and Cages?
Behind the store is Air Engineering Sales Corporation, a manufacturers’ representative and distributor that has specialized in pneumatic and mechanical conveying, process equipment, and air pollution control since the 1980s. From its base in Mountaintop, the company works with maintenance managers, plant engineers, and procurement teams to fix real dust collector problems, not just sell parts off a shelf.
That background is the reason Bags and Cages exists. The same customers kept asking for one thing: a faster, simpler way to reorder the valves, bags, and cages they already trusted. So we built the online store to do exactly that. Same parts, same people, easier ordering.

Why buy from Bags and Cages?
A few things set us apart.
First, the Goyen side. We’re an authorized Goyen Master Distributor, so the valves, solenoids, timers, and repair kits are genuine Goyen, straight from the source. When a real part matters for fit, warranty, or performance, that counts.
On the filter side, we build a quality aftermarket alternative and hold it to the same standard as the OEM, or better. Tell us the collector you run or the part number you’re replacing, and we’ll match the right bag, cage, or cartridge without the guesswork. Decades of sizing and cross-reference work sit behind that.
Air Engineering Sales has also been a Manufacturers’ Agents National Association member in good standing since 1985. It’s a small badge, but a checkable one, and it lines up with the experience we lean on every day.
And you get a person. Call and you’ll talk to someone who knows dust collectors and wants to fix the problem.
A real problem we helped solve
Back in 2008, an eastern US manganese plant kept losing production to arching in a feed bin. Two electromagnetic vibrators weren’t fixing it. They cracked the bin welds, needed replacing two to four times a year, and still left operators breaking up clogs by hand.
Working as the plant’s manufacturers’ rep, our team recommended a different fix: two EXEN Air Knockers and an air-powered timer controller. We measured the bin, drew up the install, and coordinated the parts. The Air Knockers tap the bin wall with compressed air at a set interval, so the material keeps moving without the damage the vibrators caused.
The plant got steadier flow, less manual labor, no more cracked welds, and a fast return once they stopped replacing vibrators. They even asked to add Air Knockers to their other problem hoppers.
