The Whisper Jet delivers unmatched reliability and hassle-free maintenance. The Whisper Jet cleanly and efficiently burns oil or gas and its compact flame makes it compatible with virtually all drum designs without complicated adjustments.

Whisper Jet's compact flame shape eliminates drum overheating and does not require complicated flame shape adjustments for best combustion efficiency.

The heavy-duty main fan damper is constructed to provide years of trouble-free operation.

Whisper Jet's patented design promotes more rapid mixing and combustion.

Trouble-Free Maintenance & Operation

Maintenance and downtime are virtually eliminated by the careful design of the Whisper Jet burner. The Whisper Jet burner uses the highest quality, field-proven components. Each burner is also fully tested before leaving the Astec burner factory to make start-up at your facility as fast as possible. For the most reliable oil light-off, even under cold and harsh conditions, the Whisper Jet is supplied with Astec’s exclusive heat tracing and insulation system.

Low Combustion And Noise Emissions

The Whisper Jet uses unique patented technology to burn clean and efficiently. True to its name, the Whisper Jet is designed and equipped to reduce burner noise over competitive burners.

Efficient Combustion

Rapidly swirling high energy air is the key to the Whisper Jet’s efficient combustion. The swirling air and flame are created by the fixed internal spin vanes and the patented castellated nose, ring, and nozzle design.
