Discuss the different brands and sizes of heat presses available on the market, including Hix, GeoKnight, Hotronix, and other smaller manufacturers. Topics include maintenance, selection, styles and more.
If you own this press, I have two questions for you...
1. What is the max PSI of your air compressor?
2. What air pressure settings do you use for "Heavy Pressure?"
I thought I did the RIGHT THING... before I purchased an air compressor, I called up GeoKnight and asked them what type of air compressor I needed... they gave me no specifics, but did tell me the press is low pressure/higher volume when it comes to air.
So... I bought a quiet air compressor, since it is going in a room in my garage.
Now I get the press... and see that the pressure guage goes up to 160!!!
My air compressor max's out at 115... and I am going to use imageclip papers which require heavy pressure.
So... do I need to find a new air compressor?
If you own this press... please let me know.
I am 1 week away from starting to press shirts... have 100's of imageclip papers coming... and will need to scramble to find a high pressure/low noise compressor if that is what is needed.
cubic feet per minute (cfm) is usually what you would look for in a comp.
They should have a better idea about what you need. If you get bigger that what you need it wont cycle on/off so much.
In the users guide for the Manual version of my press, there is a digital readout for pressure... and it says... 1-3 for light pressure 4-6 for medium 7-9 for heavy.
My press has NO info about pressure... just a gauge that goes from 0-160 PSI... and a rotary dial to set the air pressure.
Am I missing something?
I think it is very strange that they make no mention of pressure in the manual.

I have to say, being able to set a pre-press time is sweet...
Press two buttons... it pre-presses for a set period of time then opens.... waits for you to press the two buttons again for the main pressing time.
I still think I am in trouble... the gauge on my press is maxing out at 115psi... same as my compressor... and since the press gauge goes to 160, this is only like 65% of available press pressure.
If I find out that the platen pressure at 115psi is NOT high enough pressure for the imageclip, I think I am up a creek.
I had a hotronx draw press before, and it had to have really high pressure (9) for the best results with Imageclip.
Set the psi to 60 using the knob that is on the press. This limits the presure to 60 psi which is all the presure you need from the compressor to operate your GEO Press.
that gauge is the max air pressure that that valve will take..dont worry about but don"t max it out. your press should have a regulator built in .. or inline from the compressor. You need to figure out the maximum pressure for your PRESS ( after the regulator) can take and set it to that.
It was suggested to try it at 60 and see if that works. Does it automatically set the platen pressure ?
Dont forget the always essential water trap and air filter to keep crap out of you air valves
I hope you figure it out, looks like a nice machine from their website. I use comps/air gadgets quite often , just never on a press.
From what I can tell... Plated Pressure IS set by PSI.
60 PSI is a "4" of Platen Pressure
115 PSI (The max my compressor will do) is about "8" of Platen Pressure.
150 PSI is "10"...
... so to answer the previous post... yes, my press will run at "60" PSI... but only if I want low to medium pressure.
Imageclip is 400F with Heavy Pressure.
Another thing I didn't consider is cycling... my compressor is pre-set to cycle (turn on) when the pressure drops below 90... and turn off when it gets to 115.
Fine if you are using a nail gun... but not so good if the compressor tank pressure is determining your platen pressure.
Think I may have to look for a different compressor.
I bought my Knight press 7 years ago and was told buy the company that
40psi light, 60psi medium, 80psi firm. I have my air compressor set at
100psi max. Have use these settings for 7 years with no problems.
Hope this helps.

That would have been a great addition to the user's manual
So you have used transfer papers, like imageclip, that require "heavy pressure" without any problems?
Just get nervous when I see an air gauge goes up to 160psi... and corresponding single digit numbers 1 thru 10... AND pressure indicators (digitally) that also go 1 thru 10...
Makes me think if you need a pressure of 9, you need to have at least 140psi (according to the gauge on the press.)
cfm is what gives you the force. i have an 18.5 cfm stands as tall as me and i paid a thousand for it..it will carve granite but needs alot of cooling off because sandblasting keeps it running pretty steady..but it does have the air volume @ 100psi.
It would be overkill for you maybe but you would prob be spent 3-500 cnd. for something reasonable ... dont forget..the more it cycles, the more condensation it will produce and the more moisture that can get into your airline.
