Old prestcold fans

[Andy AC]

Does anybody remember or know what type of evap fan should fit a prestcold cnc 250 164 evap unit? Been called to a small cold room today, evap frozen solid, thawed it all out and let the fans run for a few hours to clear any remaining ice, switched it back on to cooling and found the airflow to be pants. Previous engineer has shoehorned/bodged in a couple of 7w or 10w remco multfits and roughly attached the fan blades - the ones you tighten the grub screws on. The angle on the blades is very shallow, I'd had thought that if they were the original type of blade, you would need motors with higher speed.
Any thoughts anyone?

I've recently found Polestar (Elco's direct sales outlet) on 01526 399 733 very helpful, might be worth a try if you have no luck with Install Monkeys suggestion. Would be worth getting a catalouge from them if nothing else.
