mod con intake filter build

hot_rod

Using a common K&N universal filter. No name knock-off of this filter for around 35 bucks. This model slips over a piece of 6" PVC thin walled PVC. I imagine you could find a 2" version.

The aluminum adapter plate just slips over the 2" intake PVC.

I want to keep woodworking dust out of the machine.

I doubt a manufacturer would approve this without some extended testing?

I believe you are doing the testing yourself at this point. How often would you need to service/clean/replace the filter would be determined by the amount of dust collected by the filter.

previous I pulled outside air into this boiler. It did have a number of bugs in the burner when I serviced it last year.

just moved it across the shop, thought I would try inside air this time.

But why stop at such a small filter. Why not build something that is 28" x 28" x 24" that can hold 5 filters like this:

I could rent space to my neighbors on that filter rack

what drove the move? Always curious about people change thier shops; I envisions your as a hydronics experimentation lab.

Aerco Boilers use the KN's for their Benchmark boilers. Should work for yours

K&N filters are made for an oil spray on the filter media. That's where it gets its excellent filtering without a loss of air ingestion. Its washable and re-useable. Lifetime.

As I recall the K&N has a greater filtering capacity, micron size particles, than a paper filter without compromising flow. In the long run it is cheaper than paper.

I replaced my boiler with an A2WHP, so the boiler moved to another location, but is piped for backup if needed.

Yes I do have some wall space for testing hydronic ideas and components.
