S20

• Compact in size, big on performanceand durability

• All-levers-forward operation reducesoperator training

• Unrivaled dust control performancewith the patent pending SweepMax™system and ShakeMax™ 360 technology

Compact Midsize Rider Sweeper

Improved air quality and optimum cleaningThe S20 SweepMax™ system removes the majority of dust andmoisture for superior dust control, longer filter life, and extendedsweeping time.

Focus on safetyThe Tennant S20 was engineered with a focus on safety—for theoperator, the environment, and your employees. Important safetyfeatures include excellent operator sightlines, steering wheel-mountedhorn, standard headlights and taillights, hopper support arm andthe Thermo-Sentry™.

Proven Tennant quality for long-lasting return on investmentQuality combines with easy maintenance features to make the S20an exceptionally cost-effective sweeper that you can count on foryears of reliable service.

The Tennant S20 rider sweeper sets the standard for compact sweeperperformance, safety, and value. With the sweeping power of a mid-sizeand the maneuverability of a compact, the S20 goes where you need itand gets the job done.

Maximum sweeping power when andwhere you need it

Improving air flow filtration and dust controlfor sweeping, the patent-pending S20SweepMax™ system uses a 3-stage dustcontrol system:

STAGE 1Keep bulky debris, water, and heavy dust inthe hopper with the first stage Perma-Filter™.

STAGE 2Remove fine dust and moisture by redirectingit into the hopper with the second stagecyclonic prefilter.

STAGE 3Filter sub-micron dust particulates down to0.5 microns at 99% efficiency with a thirdstage, flame retardant, nanofiber surface load-ing canister filter.

This 3-stage system filters sub-micron dustparticles to a MERV 13 rating on the ASHRAE20 point scale.

The SweepMax™ dust controlsystem lets you run longerwith optimum performance
