Gelair Air Conditioning Blocks

Gelair Air Conditioning Blocks are designed to provide continuous treatment inside ducted air-conditioning systems without adding powered equipment. Each block contains pure Australian tea tree oil in a formulated gel matrix that releases vapour into the moving airstream while the air handler is operating.

How Gelair Air Conditioning Blocks are used

The manufacturer directs the block to be removed from its foil packaging and positioned in the incoming airstream of the air handling unit, between the filter and cooling coil. The drawstring is secured to the AHU internals. Gelair’s current instructions state that the block should be removed and replaced after four weeks.

Choosing the correct Gelair block

Gelair supplies four sizes for different air-conditioning system capacities: AB0.5 (0.5 kg), AB1 (1 kg), AB2 (2 kg) and AB4 (4 kg). Select the size according to the air handler and airflow requirements rather than simply choosing the largest block.

Marine HVAC use

For yachts and boats with ducted air handlers, Gelair blocks provide a simple way to introduce tea tree oil vapour into the HVAC airstream without additional electrical load. For built-up grime on coils or duct surfaces, Gelair recommends using its Coil and Duct Cleaner rather than relying on the block as a cleaning product.

Frequently Asked Questions

Which Gelair Air Conditioning Block size should I use in my yacht's air handler?

Gelair offers AB0.5, AB1, AB2 and AB4 blocks for different system capacities. Match the block to the air handler and airflow; the existing Yacht-Mate product data identifies progressively larger blocks for larger or higher-flow air handlers.

Where should the Gelair Air Conditioning Block be installed in an air handling unit?

Gelair instructs users to place the block in the incoming airstream of the AHU, between the filter and cooling coils, and secure the drawstring to the unit’s internals.

How often should I replace a Gelair Air Conditioning Block?

Gelair’s current directions state that the block should be removed from the air handling unit after four weeks and replaced.

Does a Gelair Air Conditioning Block need electrical power or extra dosing equipment?

No additional powered dosing equipment is required. The block releases tea tree oil vapour into the moving HVAC airstream while the air-conditioning system operates.

Should I use a Gelair Air Conditioning Block to clean dirty HVAC coils?

The block is intended for sustained vapour treatment, not for physically removing built-up grime. Gelair recommends its Coil and Duct Cleaner when the air handling unit or coils need cleaning.
