Air vent increases cold condensate start-up capacity.
The FT is the product of experience.
First launched in the 1940's the FT has become the most advanced ball float steam trap available.
Constant design improvements have made today's FT an extremely robust steam trap, ideally suited to the rigorous demands of any steam system.

With over three and a half million Spirax Sarco FT traps supplied to over 100 000 customers the Spirax Sarco FT has become the most widely used ball float steam trap in the orld today.
