Replaces Bullard HC2400 Hot Tube – Breathing Air Heating Device with Belt – Clemco 04411

Replaces Bullard HC2400 Hot Tube – Breathing Air Heating Device with Belt – Clemco 04411

Improve operator comfort during cold-weather abrasive blasting and industrial painting operations with this aftermarket breathing-air Hot Tube designed to replace Bullard HC2400.

This compressed-air heating device features a garden hose thread connection and operator belt and is intended for use with compatible supplied-air respirator systems.

It also cross-references Clemco 04411, making it a useful service component for maintaining older industrial breathing-air equipment.

The Hot Tube uses compressed-air temperature-control technology to warm incoming breathing air, helping operators stay more comfortable during extended work in cold environments.

What the Hot Tube Does

The HC2400-style Hot Tube is designed to increase the temperature of compressed breathing air before it reaches the operator's respirator.

The device uses compressed-air temperature-control technology to produce a warming effect without requiring a separate electrical heating element.

This can help improve comfort during physically demanding work in cold environments, particularly when operators are wearing blasting helmets, protective capes, and other protective clothing.

Actual heating performance depends on incoming air temperature, supply pressure, airflow, and operating conditions.

Why Use a Breathing-Air Hot Tube?

Cold incoming breathing air can make extended abrasive blasting or industrial painting work uncomfortable, especially during winter or in unheated facilities.

A breathing-air heating device can provide several benefits:

• Warmer incoming breathing air

• Improved comfort during cold-weather operations

• Reduced discomfort from cold compressed air

• Convenient belt-mounted configuration

• No external electrical heating equipment required

• Useful for industrial blasting and painting applications

The Hot Tube changes the temperature of supplied air. It does not filter, purify, or improve the chemical quality of the breathing-air supply.

Garden Hose Thread Connection

This Hot Tube features a garden hose thread connection, as specified for this configuration.

Connection styles vary among supplied-air respirator systems. Similar-looking heating and cooling devices may use different fittings or require different operating conditions.

Before ordering, verify:

• Original equipment part number

• Garden hose thread connection

• Compatible breathing-air hose

• Respirator model

• Required operating pressure and airflow

• Approved component configuration

Do not assume Hot Tubes with different connection styles are interchangeable.

Common Reasons for Replacement

• Existing Hot Tube is damaged

• Heating performance has deteriorated

• Air leaks from the assembly

• Connection threads are damaged

• Existing device is missing

• Belt or mounting components are worn

• Repairing or refurbishing a supplied-air respirator system

• Restoring the original heating configuration

Applications

• Cold-weather sandblasting

• Shot blasting and abrasive blasting

• Supplied-air blasting helmets

• Industrial painting and coating operations

• Structural steel surface preparation

• Shipyard and marine maintenance

• Bridge maintenance and rehabilitation

• Tank and vessel surface preparation

• Industrial equipment refurbishment

• Unheated industrial work environments

Hot Tube vs. Cool Tube

Supplied-air temperature-control devices are available in different configurations.

Hot Tube – This Listing

• Replaces Bullard HC2400

• Cross-references Clemco 04411

• Designed to warm incoming breathing air

• Garden hose thread connection

• Includes operator belt

Cool Tube – Sold Separately

• Replaces Bullard AC1000

• Cross-references Clemco 04410

• Designed to cool incoming breathing air

• Garden hose thread connection

• Includes operator belt

These components perform different functions and should not be treated as interchangeable.

Finding Parts for Older Breathing-Air Equipment

Industrial supplied-air respirator equipment from Bullard and Clemco can remain in service for many years, while individual heating and cooling components may become difficult to identify.

That's why we include the original manufacturer part numbers, connection configuration, and intended function whenever possible.

For this component, the key identification information is:

Bullard HC2400 / Clemco 04411 – Hot Tube Breathing-Air Heating Device – Garden Hose Thread with Belt

Important

This listing is for one aftermarket HC2400-style Breathing-Air Hot Tube with garden hose thread connection and operator belt.

Cross-references:

• Bullard HC2400

• Clemco 04411

This is an aftermarket component and is not manufactured by Bullard or Clemco.

The respirator helmet, breathing-air supply hose, compressor, filtration system, and other accessories are sold separately unless specifically stated otherwise.

Always verify the original part number, connection configuration, operating requirements, and compatibility with the complete breathing-air system before ordering.

Breathing-Air Safety

This Hot Tube is a temperature-control device. It does not remove carbon monoxide, oil vapors, toxic gases, or other contaminants from compressed breathing air.

The breathing-air source must meet applicable respiratory protection requirements, including OSHA 29 CFR 1910.134.

Use only component combinations approved for the intended respirator system and follow the manufacturer's specified airflow, pressure, and operating requirements.

Because this is an aftermarket breathing-air component, its suitability for a particular respirator system must be established before use. A matching connection or OEM cross-reference alone does not establish NIOSH-approved compatibility.

Never substitute ordinary pneumatic fittings or hoses for approved breathing-air components.
