F113-008 / Gun B Configuration

Universal / Uniblast identifies this complete assembly as both:

F113-008
Gun B

The F113-008 Gun B is configured with a 5/16" ceramic nozzle and 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. This draws abrasive media through the media hose and into the mixing chamber.

The abrasive joins the compressed-air stream and is accelerated through the 5/16" ceramic nozzle toward the work surface.

Correct matching of the air jet and nozzle is important for consistent abrasive pickup and proper blast-gun performance.

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 nozzles provide an economical solution for general-purpose abrasive blasting. They're especially useful where initial cost is more important than achieving the extended wear life of tungsten carbide or boron carbide.

Ceramic is a consumable wear material, so the nozzle bore should be inspected periodically. Abrasive type, media size, operating pressure, and frequency of use can all affect nozzle life.

Checking Nozzle Wear

As a ceramic nozzle wears, its bore gradually becomes larger. This can increase compressed-air consumption and change the performance of the blast gun.

Common indications of nozzle wear include:

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

Periodically measuring the nozzle bore is a simple way to determine when the nozzle should be replaced.

Applications:

• Suction-feed blast cabinets
• General-purpose abrasive blasting
• Rust and corrosion removal
• Paint and coating removal
• Surface preparation
• 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 F113-008 – Gun B – 5/16" Ceramic Nozzle with 5/32" Air Jet

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F113-008 Gun B complete blast gun assembly with 5/16" ceramic nozzle and 5/32" air jet.

Always verify the F113-008 / Gun B designation, 5/16" nozzle size, 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.
