The Signature™ series is designed for mid to large homes where families, pets, and active daily activities will push a central vacuum system day in and day out.
- High Efficiency HEPA Filtration System that captures up to 99.97% of allergens @ .3 microns.
- Cooling Intake Muffler circulates fresh air during operation, allowing the motor to stay cool for a longer life and quiet operation.
- 3 Pack Allergen Bags are included with the LS490. One bag is included for Signature™ models LS590, LS690, LS790 and XLS990.
- Industry Leading 20-Year Warranty for an ultimate peace of mind.

TANGENTIAL BYPASS MOTOR
It’s what’s inside that counts.
When you select the Signature™ Series of central vacuum systems, you immediately take a step up with the heavy duty performance and longevity of a Tangential Bypass Motor. Unlike Flow-Thru motors which use vacuumed air to cool the motor, Tangential motors have a dedicated “fresh air” cooling fan for optimal cooling. This maximizes its life expectancy and provides Signature™ with a premium source of power.
