The Telford Smith Silencer is engineered for seamless integration with most industrial blowers, delivering meaningful acoustic attenuation where it matters most: the inlet side of the blower.

KEY BENEFITS

75% Noise Energy Reduction

• Field-tested reduction from 96 dB to 90 dB on 7.5kW blower—a meaningful improvement in operator comfort and site noise levels.

Quieter Plant Environment

• Improves communication around equipment and reduces noise complaints from adjacent work areas or neighboring sites.

Reduced Project Cost

• Less need for secondary acoustic enclosures or retrofits—a low-cost option compared to building insulation and equipment isolation.

One-Off Expense, No Running Costs

• Improves acceptance of high-capacity blowers in noise-sensitive environments with zero ongoing operational expense.

Flexible Installation

• Adaptors to suit most blower and pipe connections. 90° bends available to raise suction position off the ground—preventing blowers from sucking in rubbish and dirt.

Robust Construction

• Galvanised mild steel body for corrosion resistance in wet, dusty environments—ideal for waste, recycling, and plastics processing.

APPLICATIONS

The Telford Smith Silencer is engineered for industrial environments where noise control is essential:

• Waste transfer stations – Reduce community noise complaints at facility boundaries
• Recycling MRFs – Improve operator communication in high-noise sorting areas
• Plastics reprocessing lines – Create safer work environments near conveying systems
• Bulk bag feeding systems – Pair with Debagging Stations to reduce intake noise
• Pneumatic conveying systems – Lower ambient noise in noise-sensitive facilities

The silencer delivers the most significant reduction where it matters most: the inlet side of the blower, where noise generation is highest.

HOW IT WORKS

The Telford Smith Silencer uses a simple but effective principle: sound energy dissipates as airflow passes through an extended, baffled chamber. Our silencers add targeted length and internal geometry to absorb noise at its source—without disrupting blower performance.

Why inlet installation is standard:

• Blowers generate most aerodynamic noise at the inlet due to turbulent flow ingestion
• Inlet noise dominates the overall spectrum (especially low/mid frequencies)
• Outlet noise is more directional and often attenuated by ductwork or enclosure
• Installing the silencer on the inlet provides the best practical noise reduction per unit cost and space

EASY TO MAINTAIN

Annual Visual Inspection

• Check for corrosion, debris blockage, or loose flanges

Clean Internal Baffles

• If material carryover occurs (e.g., in high-dust applications)

No Scheduled Servicing

• Passive design ensures long service life—no moving parts to wear out

FLEXIBLE TO FIT YOUR NEEDS

This silencer is built to pair directly with most industrial blowers—reducing noise where operators work and communities listen. While it can be delivered as a standalone unit, Telford Smith also designs and supplies upstream and downstream equipment—like Debagging Stations, Pre-Cleaners, and Conveyors—configured to your specific production requirements.

90° bends enable routing in space-constrained installations and help elevate suction points away from ground-level debris.

Purpose-built by Telford Smith with the customer in mind. Proven design, built to last.

FREQUENTLY ASKED QUESTIONS

Where should the silencer be installed—on the inlet or outlet side?

The silencer is typically installed on the inlet side of the blower, where noise generation is highest. Field observations confirm inlet noise dominates the overall spectrum, especially low/mid frequencies. While outlet installation can achieve greater noise reduction in isolation, the inlet remains the dominant noise source in practical applications.

Will the silencer affect my blower's performance?

Our silencers are engineered for minimal impact on blower airflow performance. The internal geometry is designed to dissipate sound energy without creating significant pressure drop. For application-specific validation, contact our engineering team with your blower specifications.

What materials are the silencers made from?

All Telford Smith Silencers are constructed from galvanised mild steel, providing excellent corrosion resistance for wet, dusty environments typical of waste and recycling operations. This material choice ensures durability while maintaining cost-effectiveness.

Can I use these with non-Telford Smith blowers?

Yes. We hold a range of adapters in stock to suit most blower manufacturers' connections. Our engineering team can help determine the correct adapter for your specific blower model.
