Air Distribution and
Ventilation Products
Mechanical Reps Inc. provides a top-tier range of air distribution and ventilation solutions, including grilles, registers, diffusers, dampers, louvers, fans, and spiral ductwork and accessories, all designed to ensure optimal airflow and energy efficiency for commercial and industrial applications.
Greenheck Roof Mounted Fans
The model GB shown here is is a belt-driven centrifugal roof exhaust fan designed for general clean-air applications. It features a downblast discharge directed toward the roof surface and a spun aluminum housing for durability and corrosion resistance.
Price CF Slot Diffuser
Linx Spiral Duct and Fittings
Greenheck Fire Smoke Dampers
The model FSD-211 shown here is a combination fire and smoke damper featuring 3V-style blades. Designed for installation in walls, floors, or partitions, it is rated for operation with airflow in any direction, ensuring versatile and reliable protection in HVAC systems..
Greenheck Louvers
The shown ESD-435 here, protects air intake and exhaust openings in exterior walls. Its drainable head and horizontal stationary blades collect and channel water toward the bottom of the frame, where gravity assists in directing it away from the louver—enhancing weather resistance and system reliability.
Greenheck Motorized Dampers
The model VCD-23 is a general purpose control damper with 3V blades. This model can be used in applications as an automatic control or manual balancing damper with low to medium pressure and velocity systems.
- Pressure: Up to 5 in. wg
- Leakage: Class 1A @ 1in. wg, Class 1 @ up to 5 in. wg
- Velocity: Up to 3000 fpm
- Temperature: -40°F to 250°F
- Blade and jamb seals
PRICE SDV - Single Duct Terminal Unit
The SDV is a quiet, low-resistance airflow control. Its built-in airflow sensor ensures consistent volume, automatically adjusting to supply pressure changes for true pressure-independent performance.
Price Ceiling Diffusers
The Square Cone Diffuser (SCD) shown here, features an aerodynamic backpan and cone assembly that delivers a uniform 360° horizontal air pattern. It ensures rapid mixing, temperature balance, and reduced velocity with minimal pressure drop and noise. Ideal for VAV systems with high turndown ratios, the SCD maintains a stable air pattern even at low air volumes—minimizing drafts and air dumping.
