F113-009 / Gun B Configuration

Universal / Uniblast identifies this complete assembly as both F113-009 and Gun B.

The F113-009 configuration consists of a: 3/8" Ceramic Nozzle + 5/32" Air Jet

How a Suction Blast Gun Works

Compressed air passes through the 5/32" air jet, creating a low-pressure area inside the blast gun that draws abrasive media through the media hose and into the mixing chamber.

The abrasive joins the compressed-air stream and is accelerated through the 3/8" ceramic nozzle toward the work surface.

Correct matching of the nozzle and air jet helps provide consistent abrasive pickup and efficient blast-gun operation.

Air Consumption / Compressor Requirements

CFM figures are provided as a general siphon-blast compressor-sizing reference. Actual air consumption can vary with gun configuration, nozzle condition, operating conditions, and the compressed-air system.

Why a Ceramic Nozzle?

Ceramic blast nozzles provide an economical option for general-purpose abrasive blasting. They're particularly useful where lower initial cost is preferred over the extended wear life offered by tungsten carbide or boron carbide.

Ceramic nozzles are consumable wear components. Service life will vary considerably depending on abrasive type, media size, operating pressure, and frequency of use.

Checking Nozzle Wear

Abrasive passing through the nozzle gradually enlarges the bore. As a ceramic nozzle wears, the gun may require more compressed air while producing less consistent blasting performance.

Common indications of nozzle wear include:

• Enlarged or irregular nozzle bore
• Increased compressed-air consumption
• Changes in blast pattern
• Reduced abrasive velocity
• Reduced blasting efficiency
• Increased abrasive consumption
• Difficulty maintaining operating pressure

Periodically measuring the nozzle bore makes it easier to identify excessive wear before it significantly affects performance.

Applications:

• Suction-feed blast cabinets
• General-purpose abrasive blasting
• Surface preparation
• Paint and coating removal
• Rust and corrosion removal
• Cleaning fabricated and machined components
• Equipment restoration
• Industrial maintenance

Finding Parts for Older Universal / Uniblast Equipment

Universal Equipment Manufacturing and Uniblast Technologies blasting equipment has been used in industrial applications for many years, and parts for older machines can sometimes be difficult to identify.

That's why we include the original part number, gun designation, nozzle size, and air-jet size whenever possible.

For this assembly, the key identification information is:

Universal / Uniblast F113-009 – Gun B – 3/8" Ceramic Nozzle with 5/32" Air Jet

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F113-009 Gun B complete blast gun assembly with 3/8" ceramic nozzle and 5/32" air jet.

Always verify the F113-009 / Gun B designation, 3/8" nozzle bore, and 5/32" air-jet size before ordering.

Completely shut off and relieve compressed-air pressure before installing, removing, or servicing any blast gun, nozzle, air jet, hose, or related blasting component. Never operate abrasive blasting equipment with damaged or improperly secured components.
