Hoffman Specialty 404222 (FT030H-5) Float & Thermostatic Steam Trap
Engineered for continuous condensate discharge and high-capacity air venting in low-to-medium pressure steam heating systems, the Hoffman Specialty 404222 (Series FT030H-5) is a heavy-duty Float and Thermostatic (F&T) steam trap designed for industrial and commercial steam applications. Featuring a 1-1/4" NPT female threaded body and a 30 PSI maximum operating pressure differential, this unit excels in steam main drips, unit heaters, heat exchangers, and boiler system heat transfer equipment.
The FT030H-5 series utilizes a stainless steel float and lever mechanism paired with a balanced-pressure thermostatic air vent element. This dual-action design allows non-condensable gases and air to vent rapidly during system startup while providing instantaneous, modulated discharge of hot condensate under varying load conditions without steam loss.
Key System Performance Baselines:
- Continuous Modulated Discharge: Modulating ball float mechanism responds immediately to condensate load changes to maintain maximum heat transfer efficiency.
- Integrated Thermostatic Air Vent: Heavy-duty air element exhausts non-condensable gases fast to prevent air-binding during cold system startups.
- In-Line Maintenance Footprint: Cast iron body construction with accessible internal components permits servicing and cleaning without removing the trap body from the piping network.
- Stainless Steel Trim: High-grade stainless steel internal float, valve seat, and mechanism resist erosion and water hammer damage.
⚠️ Application Profile: Ideal for steam unit heaters, air handling coil units, steam heat exchangers, boiler header drips, and commercial hydronic/steam process equipment requiring 30 PSI differential capacity.
