Our Products

The Volume Control Damper  are constructed using double skin interlocking aerofoil blades, which in conjunction with stainless steel side seals provide positive control and shut off.

A multi-blade opposed action format utilizes a fully enclosed linkage system, which is located outside the airstream, to ensure minimum ingress of airborne containments.

Dampers come in a variety of designs. Opposed blade dampers use a motor to open and close them. This damper design has the appearance of accordion or folding panels when closed, and metal slots when open.

Single blade dampers can use a motor to open and close them, or use a spring to close and a motor to open. This type will remain in the closed position at rest.  A single blade with spring open uses the motor to close, and is open at rest.

Access Doors, as the name implies, are useful for providing access to an area that requires some level of protected entry. Access Doors, also called Access Panels, are used in a wide variety of applications including drywall, plaster, fire-rated, and universal. Access Doors come in a number of different materials to meet design and specification needs.

Access Door can be used to provide easy access to plumbing fixtures, ceiling spaces, roof access, special enclosures, and many others.

Sand trap louvers have been specifically designed to allow airflow into buildings and at the same time repel the entry of dust and sand where these elements are natural hazards. Manufactured from Pre-coated steel material the units are designed and tested to withstand the most arduous conditions over many years.

Installed vertically in buildings these units provide a unique feature visually but perform an important element in ventilation design.

Non return dampers are designed for automatic shut off of individual sections of an air conditioning system.

With the fan running, the degree of blade opening is a function of the air velocity. If the fan is turned off, the blades close automatically. In a multi fan installation this prevents back draught through the non-operating fans.

Flowline is a custom architectural linear diffuser system designed to integrate and blend supply and return air openings into interior commercial bulding designs.

Flowline may be used to either inconspicuously hide the air distribution system or conversely it may be used as a contrasting, architectural design element, using straight lines and or curves to enhance the interior of a building.

The Nailor line of Plenum Slot Diffusers have been designed to integrate and blend with T-Bar suspended grid systems.They are available for Standard Lay-in T-bar systems as well as the narrow Regressed T-Bar systems.

Four different styles are available in a wide range of sizes and capacities for an optimum combination of application flexibility and performance requirments.

Nailors New 1600 Series Louvers combine architecturally enhancing aesthetics with excellent performance characteristics.

This commitment has helped foster industry stnadsrds, as well as provide worry free fire protection solutions that benefit todays builidngs designers , owners and occupants.

Variable Air Volume Systems supply a constant temperature to an area and vary as opposed to a conventional HVAC sysytem which supplies a constant volume and varies the air temperature.

Operating costs are greatly reduced compared to the larger conventional HVAC systems by using less fan energy and less refrigeration energy. Variable Air Volume systems also cut inital cost by taking advantage of building diversity.
