The VacuMaid SR46 combines powerful cyclonic cleaning, quiet 60 dB operation, flexible collection options, and durable American-made steel construction for homes up to approximately 9,500 square feet.

Features:

• Up to 9,500 Sq. Ft. Coverage – Designed for large residential central vacuum installations.

• 663 Max Air Watts – Provides strong whole-home cleaning performance throughout an extensive piping system.

• 132-Inch Water Lift – Delivers powerful suction for carpets, hard floors, furniture, stairs, and everyday cleaning.

• 139 CFM Airflow – Moves a high volume of air to efficiently carry dirt and debris through the central vacuum tubing.

• 6.6-Inch 2-Stage By-Pass Motor – Heavy-duty motor design uses separate cooling airflow for dependable long-term performance.

• Quiet 60 dB Operation – Runs noticeably quieter than many high-capacity central vacuum power units.

• Cyclonic Filtration – Uses centrifugal airflow to separate dirt and debris from the incoming air stream.

• Multiple Collection Options – Use the system as a pure-dump cyclonic unit or add a compatible 5-layer filtration bag or can liner.

• 27-Quart Capacity – Provides generous dirt storage between emptying intervals.

• Galvannealed Steel Construction – Durable steel body is designed for long-term strength and corrosion resistance.

• Powder-Coated Exterior – Adds a tough protective finish for years of permanent installation.

• Right or Left Intake Installation – Gives installers more flexibility when routing central vacuum tubing.

• Built-In Utility Valve – Allows a compatible vacuum hose to connect directly at the power unit for convenient nearby cleaning.

• 120-Volt Operation – Designed for standard 120-volt electrical installation.

• 10-Year Warranty – Backed by VacuMaid’s long-term warranty coverage.

• Made in the USA – Manufactured by Lindsay Manufacturing in Ponca City, Oklahoma, a company producing central vacuum systems since 1956.

The VacuMaid SR46 is built for homeowners who want strong central vacuum performance in a large home without stepping up to the larger SR60.

Its combination of 663 air watts, 132 inches of water lift, and 139 CFM of airflow gives the SR46 the suction and airflow needed to move dirt through long piping runs while maintaining effective cleaning at the hose.

One of its standout advantages is its 60 dB sound rating, giving it strong large-home performance while operating more quietly than many higher-output central vacuum units.

The SR46 also gives you flexibility in how collected dirt is handled. Use it as a traditional pure-dump cyclonic system, add a compatible multi-layer filtration bag for more contained disposal, or use a can liner for easier cleanup.

Powerful Large-Home Performance

A central vacuum must maintain both suction and airflow across an entire piping network.

The SR46 produces up to:

• 663 Max Air Watts

• 132 Inches of Water Lift

• 139 CFM of Airflow

This balanced combination provides strong performance for larger homes and longer central vacuum tubing layouts.

6.6-Inch Two-Stage By-Pass Motor

The SR46 uses a 6.6-inch two-stage bypass motor.

A bypass motor uses separate airflow to cool the motor instead of relying on the dirty vacuum air passing through the system.

This design is well suited for permanently installed central vacuum systems where durability and sustained performance are important.

Quiet 60 dB Operation

The SR46 operates at approximately 60 dB, making quiet performance one of its strongest features.

Because the power unit is normally installed away from the main living areas, such as in a garage, basement, or utility room, the sound heard inside the home while vacuuming can be significantly reduced compared with carrying a portable vacuum motor from room to room.

Cyclonic Filtration

The SR46 uses cyclonic separation to remove dirt from the incoming airflow.

As debris enters the power unit, centrifugal force helps separate heavier particles from the air stream and directs them into the collection bucket.

This provides a simple, effective collection system with flexible maintenance options.

Flexible Collection Options

The SR46 can be configured around your preferred dirt-disposal method.

Choose from:

• Pure-Dump Cyclonic Collection – Empty debris directly from the bottom bucket.

• 5-Layer Filtration Bag – Helps keep collected dust contained during disposal.

• Can Liner – Makes routine bucket cleanup easier.

This flexibility is especially useful for customers who want the performance of a cyclonic system but prefer the cleaner handling of a disposable bag.

27-Quart Collection Capacity

The SR46 provides a generous 27-quart dirt capacity.

That gives it much more collection space than a conventional portable vacuum and reduces how frequently the system needs to be emptied.

For larger homes, that means fewer interruptions during normal maintenance.

Durable Steel Construction

VacuMaid builds the SR46 from rolled galvannealed steel rather than lightweight plastic.

The steel body provides long-term strength, while the powder-coated exterior adds corrosion resistance and protects the finish.

This construction is well suited for a central vacuum system intended to remain permanently installed for many years.

Tangential Exhaust

The SR46 uses tangential exhaust to direct motor exhaust efficiently away from the power unit.

When the installation allows, exhaust can also be routed away from occupied living areas for an even cleaner and quieter whole-home vacuum setup.

Flexible Right or Left Intake

The vacuum intake can be installed on either the right or left side of the power unit.

This gives installers greater flexibility when routing tubing and positioning the SR46 in garages, basements, utility rooms, or mechanical areas.

Built-In Utility Valve

A utility valve is built directly into the power unit.

This allows a compatible vacuum hose to connect at the SR46 itself, making it convenient for cleaning garages, workshops, basements, or the immediate area around the installation.

Made in Oklahoma

VacuMaid central vacuum systems are manufactured by Lindsay Manufacturing in Ponca City, Oklahoma.

The company has produced central vacuum systems since 1956, with a focus on durable metal construction and serviceable systems designed for permanent installation.
