Drainvac Central Vacuum Power Units
High-Performance Built-In Vacuum Systems for Powerful Whole-Home Cleaning
Upgrade your home cleaning experience with Drainvac central vacuum power units—engineered for powerful suction, quiet operation, and long-lasting reliability. Manufactured by Drainvac, these central vacuum systems are designed to deliver superior performance while improving indoor air quality and convenience.
Whether you’re replacing an older system or installing a new built-in vacuum, Drainvac power units provide the strength and durability homeowners expect from a premium central vacuum brand.
Why Choose a Drainvac Central Vacuum Power Unit?
A central vacuum power unit is the heart of your system. It generates the suction power that removes dirt, dust, and debris from every room in your home. Drainvac units are built with high-performance motors and advanced filtration systems to ensure consistent, reliable operation.
Key benefits include:
Strong, consistent AirWatt performance
Long-lasting motor durability
Quiet operation compared to portable vacuums
Improved indoor air quality
Low-maintenance design
Because central vacuum systems vent exhaust air away from living spaces, they help reduce recirculated dust and allergens inside your home.
Powerful Suction for Every Home Size
Drainvac central vacuum power units are available in a range of capacities to suit:
Small homes and condos
Mid-size residential properties
Large multi-level homes
Homes with pets or heavy traffic
Choosing the right power unit ensures optimal suction, proper airflow, and efficient cleaning throughout your entire piping system.
Advanced Filtration & Bagged Options
Many Drainvac power units feature advanced filtration technology, including:
Hybrid systems (bag or bagless operation)
High-efficiency washable filters
Sealed systems for improved dust containment
These features help protect the motor, maintain airflow, and extend the lifespan of your system.
Built for Long-Term Performance
Drainvac systems are known for durable construction and high-quality components. Proper installation and routine maintenance allow these central vacuum power units to deliver dependable performance for years.
Ideal for:
New construction installations
System upgrades
Replacing outdated or underpowered units
Homeowners seeking improved suction and air quality
Upgrade Your Central Vacuum System Today
If your current system is losing suction, running louder than normal, or struggling to keep up with your cleaning needs, it may be time to upgrade your power unit. A new Drainvac central vacuum system restores performance, improves efficiency, and enhances overall home cleanliness.
Browse our selection of Drainvac central vacuum power units to find the right model for your home. Our team can help you choose the ideal AirWatt capacity and configuration for maximum cleaning performance.
Drainvac Power Units now feature a studio-quality acoustic sound-suppressing foam inside the canister to reduce the decibel level while the vacuum is on. The canister is also constructed with a polyethelyne ABS material which also reduces noise when compared to metal-canister central vacuums, which rattle and vibrate when operating. Some models are as quiet as 56 decibels, making it the quietest central vacuum in the industry!
