     I want to try making a Quad for the first time. Basically following to same process as Allagash outlines  in Brew like a Monk. My question is, how much pressure is needed to push to beer through a 1 micron filter cartridge. I don't own kegging equipment and am wondering if there is any other way to do this. Air pressure on a sealed pail? It will get new yeast for bottling. Thanks for any suggestions.

Why do you want to filter?

Not sure about the low-tech methods. Definitely do not use compressed air. You'll oxidize your beer. Use co2 or nitrogen. That will require a tank and regulator along with an inline filter. If you have that you might as well have a couple kegs too. Check with your LHBS. Mine rents a filter for $20. Still too much? Try finings. Still too much? Store at as cool a temperature as possible until it's clear. If you want it clear fast, I'd go with finings like isinglass or biofine. Filtering beer, as I understand it, will strip out some flavor.
If it were my quad, I'd just give it time. Because a quad needs time to develop to it's full potential anyway.

Even really finicky yeast will drop pretty clear in the time frame you're looking at before a Quad hits its prime.

+1.  The time frame needed to age a quad would have it pretty clear by then. Plus, quad is a style built upon layers of flavor, and I wouldn't risk stripping any flavor away. Not a filtering fan.

Basically following the process of Allagash 4. After the 1st. three yeasts have done their work, they filter our the yeast and add a fourth bottle conditioning.

Following the processes of a brewery is not a guarantee of replicating their beer. In fact, doing so at a homebrew level will most likely end in failure. Best of luck. Try cold crashing instead.
