Description

The 1.50 GPH 90° Type A Hollow Cone Fuel Nozzle (typically identified by a red protective cap) is a professional-grade heating and combustion component. It serves as a vital replacement part for the burner assemblies of hot water pressure washers, commercial boilers, and oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a 1.50 GPH flow rate and a wide 90° spray angle, this nozzle provides a precise, medium-capacity thermal output engineered specifically for short, wide, or compact combustion chambers that utilize a hollow cone flame profile.

Key Features

• Type A Hollow Cone Pattern: Distributes atomized fuel droplets primarily around the outside of the spray cone, leaving a hollow center. This configuration matches specific burner air patterns, offering smooth ignition, excellent flame stability, and reduced smoke or soot production.

• Wide 90° Spray Angle: Provides a shorter, wider flame profile than narrower angles (like 60° or 80°), making it the perfect choice for compact, shallow, or round heating coils and combustion areas where flame impingement on deep walls must be avoided.

• Premium Bi-Metal Construction: Features a heavy-duty brass body for rapid heat dissipation (preventing fuel varnishing and residue buildup) combined with a precision-machined stainless steel internal metering section for maximum wear resistance.

• Integrated Sintered Filter: Equipped with a built-in mesh strainer at the base of the nozzle body to capture microscopic sediment, rust, and fuel impurities before they can reach the orifice, maintaining a consistent flame profile.

• Color-Coded Red Cap: Standardized color coding indicates a “Type A Hollow Cone” nozzle configuration, allowing technicians to quickly identify the correct pattern type during routine maintenance.

Common Applications

• Hot Water Pressure Washers: Utilized in commercial hot water pressure washers that feature short, wide burner configurations requiring a wide, hollow-cone flame profile to efficiently heat water flows without burning the coil walls.

• Oil Burners & Furnaces: Installed in residential and commercial heating systems running on standard heating oils, #1 diesel, #2 diesel, or kerosene.

• Boilers & Water Heaters: Used in facility, agricultural, and industrial heaters requiring a reliable, consistent, and wide-angle fuel atomization pattern.
