Maxitrol 13A03-3 Vent Screen

The Maxitrol 13A03-3 is a precision-engineered 3/8" NPT vent screen designed for critical integration within gas pressure regulator systems. Featuring a high-grade 40 mesh vent screen, this component functions as a vital flame arrestor when installed in the regulator vent outlet. Its primary technical purpose is to mitigate risks by preventing the ignition of gas-air mixtures that may accumulate in the upper diaphragm chamber. Built from corrosion-resistant brass, the 13A03-3 ensures long-term debris protection and industrial gas safety without compromising the essential "breathing" capacity of the regulator. As a standard Maxitrol regulator accessory, it maintains consistent atmospheric pressure equalization for the diaphragm, which is necessary for accurate downstream pressure regulation. For field technicians, this 3/8 inch NPT safety screen provides a rugged, threaded solution to prevent insect ingress and particulate blockage in demanding boiler room and mechanical environments, ensuring system reliability and code compliance.

• Flame Arrestor Protection: Specifically designed to prevent the ignition of hazardous gas-air mixtures within the regulator housing.
• 40 Mesh Filtration: The 40 mesh screen effectively blocks debris, dust, and insects from entering the vent line, maintaining clear airflow.
• Corrosion-Resistant Brass: Robust material selection ensures durability and performance in high-moisture or industrial HVACR environments.
• Threaded 3/8" NPT Connection: Standard sizing allows for seamless integration into Maxitrol gas regulators and 210D series models.
• Operational Stability: Ensures the regulator diaphragm can respond accurately to pressure changes by preventing vent clogs.

What happens if the Maxitrol 13A03-3 is missing from a regulator?
Without this 40 mesh vent screen, the regulator vent is susceptible to blockage from nesting insects or debris, which can cause the regulator to lock up or respond sluggishly. It also acts as a critical safety barrier against internal ignition.

Is the 13A03-3 compatible with all gas types?
Yes, this brass vent screen is compatible with natural, manufactured, mixed gases, liquefied petroleum gases, and LP gas-air mixtures typically managed by Maxitrol industrial regulators.

How do I install the 13A03-3 vent screen?
The part features a standard 3/8" NPT thread and should be hand-tightened into the vent port of the regulator. Always ensure the vent is pointed downward or protected from direct weather for optimal performance.
