I have a clarke se16c100 and recently bought an airfed mask, it keeps up but runs approx 50% of the time would it be better to reduce pressure to 8 bar to keep compressor cooler as the paint on head has discoloured which I presume is down to heat. The mask whistle never sounded so it kept up fine but I am aware that constant running is not best for it. If this would be better I could fit a second pressure switch at 8 bar and then just turn on whichever one is required dependant upon usage. I also have the offer of a 150litre tank for free from work so this would increase running time but also give longer cooling time in between so would this be of benefit as well.
