Description

The 2.75 GPH 90° Type A Hollow Cone Fuel Nozzle (typically identified by a red protective cap) is a high-capacity, professional-grade combustion component. It serves as a vital replacement part for the burner assemblies of heavy-duty hot water pressure washers, commercial boilers, and large oil furnaces, where it atomizes fuel to ensure highly efficient, clean, and stable heat generation.

With a substantial 2.75 GPH flow rate and a wide 90° spray angle, this nozzle delivers high thermal output into short, wide, or compact combustion chambers designed specifically around 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 even at higher fuel capacities.

• 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 internal clogs) 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 an uninterrupted 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.
