Why a Venturi Nozzle?

A venturi nozzle uses a shaped internal passage to accelerate and expand the abrasive/air stream as it passes through the nozzle.

Compared with a conventional straight-bore nozzle, the venturi design can provide a broader, more efficient blast pattern, making it particularly useful for production work and cleaning larger surface areas.

Why Boron Carbide?

Boron carbide is an extremely hard and wear-resistant nozzle material.

Its excellent resistance to abrasive erosion makes it particularly well suited for:

• Production blast cabinets
• Frequent or continuous blasting
• Aggressive abrasive media
• Industrial surface preparation
• Applications where extended nozzle life is important

Actual nozzle life will depend on abrasive type, media size, operating pressure, and blasting conditions.

How a Suction Blast Gun Works

Compressed air passing through the 5/32" air jet creates a low-pressure area inside the blast gun, drawing abrasive media into the gun through the media hose.

The abrasive mixes with the compressed-air stream and is accelerated through the 5/16" boron carbide venturi nozzle toward the work surface.

Correct matching of the nozzle, air jet, abrasive supply, and compressor capacity is important for efficient media pickup and blasting performance.

Air Consumption / Compressor Requirements

CFM figures are provided as a general siphon-blast compressor-sizing reference. Actual air consumption may vary with gun configuration, nozzle design, operating conditions, and system condition. Your compressor must maintain adequate CFM at the desired operating pressure for proper abrasive pickup and blasting performance.

Applications:

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

Checking Nozzle Wear

Even a boron carbide nozzle will eventually wear.

As the nozzle bore becomes enlarged, the blasting system may require more compressed air and its performance can change.

Common indications of nozzle wear include:

• Increased compressed-air demand
• Changes in blast pattern
• Reduced blasting efficiency
• Increased abrasive consumption
• Reduced abrasive velocity
• Difficulty maintaining operating pressure

Periodically inspecting and measuring the nozzle bore can help identify excessive wear before it begins significantly affecting system performance.

Finding Parts for Older Universal / Uniblast Equipment

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

That's why we include the original manufacturer part number and complete gun configuration whenever possible.

For this assembly, the key identification information is:

Universal / Uniblast F113-023 – 5/16" Boron Carbide Venturi Nozzle with 5/32" Air Jet

Important:

This listing is for one Universal Equipment Manufacturing / Uniblast Technologies F113-023 complete blast gun assembly with 5/16" boron carbide venturi nozzle and 5/32" air jet.

Always verify the F113-023 part number, nozzle size, nozzle type, and air-jet size required for your equipment before ordering.

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