Commercial HVAC Noise Control

COMMERCIAL HVAC NOISE CONTROL
VAW Systems uses a systems approach to applied noise control engineering. Our silencers are adapted to your mechanical system – not the other way around. VAW Systems works closely with Mechanical Engineers and Acoustic Consultants in the analysis and product selection for their most challenging applications. There are a number of construction options and accessories available that may be selected for any application, including high pressure systems, dirty or corrosive airstreams, cleanable silencers and access doors. Overall geometry may be varied to meet installation space limitations.

The VAW Systems Advantage

The direct benefits of the VAW Systems – Systems Approach includes space and weight reductions, significantly reduced operating costs for the facility owner, and an enhanced overall system design for Engineers. Since our silencers are integrated into the mechanical system design, the reduction or elimination of duct transitions and other fittings often results in a near equivalent total up-front cost.

Commercial Products

ABSORPTIVE SILENCERS

Absorptive Silencers

Standard absorptive silencers (acoustic baffles filled with absorptive acoustic grade media) may be applied to most HVAC and fan ventilation systems within a commercial building.  These products provide a broad-band range of attenuation using aerodynamically shaped baffles.

LINED SILENCERS

Lined Silencers

For airstreams that include high levels of moisture, particulate and other contaminates related to Indoor Air Quality concerns, these products ensure that fibrous media particles from the silencer do not enter the airstream. Typical lined silencer applications include health care facilities, laboratories, and air intakes at critical building openings.

REACTIVE (NO MEDIA) SILENCERS

Reactive (No Media) Silencers

The acoustic baffles are specially designed to tune at critical frequencies found in today’s HVAC systems for optimal Indoor Air Quality performance. The silencer package does not include any fibrous media fill. Typical reactive silencer applications include operating rooms, laboratory exhausts, clean rooms, and pharmaceutical and food processing facilities.

AXIAL FAN SILENCERS

Axial Fan Silencers

Axial fans are often employed in shaft and tunnel ventilation systems. Circular silencers, with center body pods matched to the fan and motor hub, deliver uniform flow in and out of the fan. VAW Systems’ Axial Cone Silencers are designed with a shape and size to ensure that the pressure drop is minimized (often near zero pressure losses), while helping the fan achieve the required thrust performance and noise criteria.

ACOUSTIC LOUVERS

Acoustic Louver

These products are designed to provide optimal acoustic performance (Transmission Loss) with minimal airflow restrictions (pressure drop) for your building and equipment ventilation applications. Standard acoustic louvers are manufactured from galvanized metal to suit any ventilation opening size. VAW offers a choice of finishes and built materials.

ACOUSTIC ENCLOSURES AND PLENUMS

Acoustic Enclosures and Plenums

VAW Systems acoustic enclosures and plenums are engineered for optimum attenuation and noise reduction. The enclosures may house noisy equipment, while plenums may be connected to a fan discharge or return opening to aid in the distribution of ventilation or conditioned air.

Model PHFS-1200

GRILL SILENCER

The VAW Systems Grill Silencers (RSG) are a space saving, cost-effective solution that delivers valuable sound isolation among adjacent spaces. This compact silencer (typically 4in deep) may be installed within a common plenum (ceiling or underfloor), easily integrated into the wall partition. The grill silencer may also be installed behind a ceiling air opening.

Model PHFS-1200

Return Noise Shield

The VAW Systems Return Noise Shield is an efficient, cost-effective solution that delivers valuable sound isolation among adjacent and nearby spaces that share a common ceiling plenum. The RNS is also effective at reducing mechanical system noise, such as a nearby (open return) air handling unit over a ceiling plenum.
