MFA Drain Traps

Features of Design:
The traps are fitted with a strainer and the valve acts both as a check against back pressure and as a relief valve against excess system pressure thereby protecting the internal parts. Types MFA-1 and MFA-2 are fitted with dual inlet and outlet connections enabling horizontal, vertical or angle installation.

Range and Duties:

Type	Orifice	Max Temperature	Pressure Range
MFA-1	7/32 in (5.5mm)	0~8.5 bar
MFA-1	7/32 in (5.5mm)	0~8.5 bar
MFA-2	7/32 in (5.5mm)	0~14 bar

Compressed Air Drainage
In much the same way as steam, but for quite different reasons, compressed air gives up moisture as it cools. The act of compression raises the temperature of the air and even when passed through an after-cooler, it still has heat to lose before reaching the point at which it is used.
Water vapor carried in compressed air condensates and collects in the bottom of receivers, tanks or separators, and in low points in compressed air lines. If such accumulations are not removed, the passing air will pick up moisture, which may cause rusting, sticking or spoiled work.

Typical Applications:
The uses of compressed air fall, very roughly, into two groups. It is used for power, for pneumatic tools, air operated chucks and cutters, etc. and it is used for blowing on to surfaces, for example in foundries for blowing moulds and in paint shops for spray painting. Fir use in the former group it is generally sufficient to remove the water which has already separated from the air; the the latter the ideal is to remove even the particles of water being carried in the air steam.

Connections:
• MFA-0: Screwed 1/2 in and 3/4 in (15mm and 20mm) BSP or NPT.
• MFA-1 Screwed 1/2 in. 3/4 in and 1 in (15mm, 20mm and 25mm) BSP or NPT.
• MFA-2 Screwed 3/4 in, 1 in, 1 1/4 in and 1 1/2 in (20mm, 25mm, 32mm and 40mm) BSP or NPT.
