Anita, there appear to be a number of air compressor companies that have Matrix in their product line. Maybe you could be a bit more specific about the air compressor... model number, horsepower, both would help.

When you say air filter, are you talking about the intake air filter on the compressor pump head?

And, how do you know that the air filter element needs to be changed?

Could you post your response as a comment so I can follow our discussion?

Cheers,

Bill

Recommend in-line air filters

by Don Hulsey
(El Dorado Springs, MO 64744)

I just purchased a Dewalt D55618 air compressor.

The manual says I need an in-line air filter to keep water and oil out of the airstream.

Please recommend 1 or 2 as may be the case. I plan to buy a small spray gun to spray finish on mostly small wood projects.

Most of the use for the compressor will be to blow out dirt etc from parts and air up tires etc.
Thanks,
Don
PS please include part numbers and prices

Don, when I was building air circuits, I would have an air filter at the compressor discharge, and another at the bottom of every drop tee to any application.

Reason being, even though the filter at the compressor discharge would take out the free water there, it didn't remove vapor, which would condense in the lines on the way to the various in-plant applications, and there would be more water to remove at each of those applications.

Your compressor likely only came with a regulator and discharge coupler into which you would plug your air line connector.

Install a mini-filter before the regulator, so that air entering the regulator is drier.

If you are spraying lacquer or finish onto wood working projects, you'll want an air filter before the gun, and quite likely an in line air drier to remove vapor to keep "fish eyes" out of your finish.

My advertisers would love to sell you filters. Check with them regarding price and delivery if you would.

Cheers,

Bill

Filters for instrument and mask air

by Vilas Nale
(India)

We have Centralised compressed air plant supplying Instrument air & Mask/service air for use in power plant. The mask air & inlet to dryers supplying instrument air is tapped off from outlet of common air receivers. The requirement of both type of air is similar i.e.20Nm3/min. The requirement of filters for Mask air is of 3 micron rating whereas those for instrument air is of 5 micron rating as per international standards.

I would like to know whether we can make both filters of 3 micron rating to have standardised filter elments for both type of filters.

What will be the effect on O&M of filters for dryers? What are the penalties or advantages of making both filers of 3 micron rating?
________________________

As far as I am concerned, there is absolutely no negatives to supplying cleaner air to any application, whether instrument air, or to run an air tool or cylinder.

The issue for you will be cost to maintain the 3 micron system and getting 3 micron compressed air filters that have enough flow rating for your applications.

General purpose compressed air filters run around 30-50 microns in element size.

You should always install a general purpose filter upstream from a finer filter element, including your 3 micron filters, as the general purpose filters strip larger contaminants from the compressed air before they can get to, and quickly plug up, the finer size of the element in the 3 micron filter.

As long as you are satisfied with the maintenance issues regarding just using 3 micron filters, go ahead.

I suspect that you'll be changing them out quite often, though. And do make sure you have some sort of delta P gauge on the filter so you can tell when the element is becoming plugged, and before you starve your applications for air.

Bill

Air operated water drain system blew apart.

by Paul Woods
(Waco TX)

I need to know how the diaphram line hooks back up?? I don't know where they blew off of.
Can you help?

__________________________________

Compressed air filters with carbonate bowls sometimes do fail, this often due to them being weakened by attack from compressor oils.

I don't know how to hook up the line, as I don't have your air compressor in front of me.
Please start a new thread, and upload photos so I can see your air compressor and help resolve the problem.

Cheers,

Bill
