Air regulator preference ??

[NLz]

I have quotes from Equilibar and from Microair.

Any thoughts on these companies and their equipment?

Thanks in advance,

Have only used Microair so can't speak to the other one. Microair (OLC) has been around a long time and specializes in extrusion controls.

We have had zeor issues with both their manual and automatic unit and use one ot the other on every line.

Thanks Louis,

I do low shore tubing from TPV and TPU. Max diameter is 1/2 inch, down to (someday) .06 and smaller ID. I am getting good results with about 1/2 inch of WC.

Equilibar has unboxed systems which look pretty well engineered. Microair is a bit more expensive but come in an enclosure.

Any thoughts on doing tubing .030 diameter with an ID of about .010" air pressure wise ?? Is this going to drive me nuts? I'm alreaady crazy...

Thanks,
Nelson

What is that steering wheel doing on your fly? Why it's driving me nuts. Old joke for sure.

0.030 x 0.010 should not be an issue. As to the amount of air, that depends on your draw down balance more than your draw down ratio. A negative DDB will need no air, and a positive DDB, over 1.15 will need much air. Of course tank position comes into play, the longer your air gap is, (distance from die to cooling tank) the greater the affect a given air setting will have on your tube. TPU might like a draw down ratio (using diameters) up to 2 to one and a DDB around 1.05 and maybe a little hot water in the first tank

wow that's BAD

you must have got that one from my brother...!

You brought it up

Most of the "low pressure" regulaters (inches of water) have a pressure release devise, are motor controlled and come in a small cabinet. I suppose one could build one from components, by why reinvent the wheel?
