Built for low flow
A compact trap for drainage and tracing that fits a universal connector.
No moving parts
Works on a hydrodynamic principle with sized venturis. There is no disc, float or bimetal to wear out.
Universal connector
Designed to fit a universal connector, with its own connection gasket (G-7).
In-line maintenance
Integral strainer and removable nozzle. The body does not have to be removed for maintenance.
CF8M stainless steel
CF8M cast body and 316 stainless steel nozzle cap, with 100 barg PMA.
Steam line drainage
Drip legs on headers and distribution lines, where condensate arrives at low, continuous flow rates.
Steam tracing
Steam tracers on process lines, instruments and tanks that must be kept at temperature.
Compare the connections
The versions share the design and main components. The connection changes, and with it the operating limits.

Frequently asked questions
What maintenance and engineering teams ask us most about the QF trap.
What applications is the Fenix QF steam trap designed for?
Low-flow applications such as line drainage and steam tracing, on installations with a universal connector.
What is the maximum operating pressure of the QF?
QF: 435 psig (30 barg) at 500 °F.
What sizes and connections does the QF come in?
Connections: Universal connector.
How is the QF maintained?
The integral strainer and the nozzle come out without removing the body from the line. The optional drain valve allows easy strainer cleaning (recommended up to 20 barg).
What warranty does the Fenix QF trap have?
The Fenix QF trap has a 15-year warranty. Its strainer, designed and made by Fenix, is also guaranteed for 15 years.
Why does the trap strainer matter?
Particles carried by the steam, such as rust, weld slag and scale, can block the nozzle. A robust, efficient strainer keeps the trap working properly. That is why Fenix designed and makes its own strainer and guarantees it for 15 years.
What is the drain valve for?
It is an optional accessory that allows easy strainer cleaning. When opened, line pressure blows out the sediment held in the screen without opening the cap. It is recommended for traps operating at no more than 20 barg.
What spare parts are available for the QF?
Strainer filter (F-S), Cap gasket (G-4), Nozzle gasket (G-1), Connection gasket (G-7).
Fenix strainer, designed and made by Fenix
A trap only works well if the condensate reaching it is clean. That is why Fenix designed and makes its own strainer, and guarantees it for 15 years, the same as the trap.
Protects the nozzle and venturis
Rust, weld slag and scale carried by the steam are among the most common causes of trap failure. The strainer holds them back before they reach the nozzle.
Robust by design
Stainless steel screen housed in the CF8M cast body, with a 304L stainless steel strainer cap.
Cleaning without removing the trap
The screen comes out through its cap; the trap body stays installed in the line.
Optional drain valve
An accessory that allows easy strainer cleaning: when opened, line pressure blows out the sediment held in the screen without opening the cap. Recommended for traps operating at no more than 20 barg.
Trap and strainer from one maker
Both are designed and made by Fenix, and both carry a 15-year warranty. No generic third-party strainer.
