We having an package IR air compressor with an DPT (honeywell ST3000) installed at suction. Both the tapping have been taken from same pipe (opposite sides) after suction filter and normally it shows 2-3 mmwc where as range is 800mmwc. If I open HP tapping to atmosphere, it shows 200-300 mmwc.
Could any one pls help? what is correction installation procedure to install a DPT at air compressor suction filter with UPSTREAM as atmosphere and DOWNSTREAM as suction pipe?
