Polivac SV25 GEN II Sandivac Slow Speed Sander

Upgrade to the Next Generation with the Polivac SV25 Gen II Slow Speed Sandivac

The trusted SV25 Sandivac has been rebuilt from the ground up for the demands of modern professional floor sanding. The Polivac SV25 Gen II replaces the standard helical Polidrive gearbox with a heavy-duty triple planetary industrial gear drive, the strongest gearbox configuration available for grinding and sanding applications. The Gen II further adds all-metal motor cowl and capacitor boxes that protect critical components far better than the plastic equivalents found on other machines.

Running at 212 RPM — slightly faster than the original SV25's 188 RPM — and weighing in at 51 kg with an additional 3 kg weight set included, the Gen II delivers more downward pressure and more controlled cutting power in a machine built to last significantly longer than its predecessor. 

Key Benefits & Features of the Polivac SV25 Gen II Sandivac

• Triple planetary industrial gear drive — the strongest gearbox available — The Gen II moves beyond the standard helical gearbox to a long-life triple planetary gear drive with a 6.8:1 ratio, proven across the most demanding grinding and sanding applications. It's a fundamentally stronger gearbox design that delivers quieter, more positive power transfer and significantly outlasts conventional single-reduction gearboxes.

• All-metal cowl and capacitor boxes for superior component protection — Where other machines rely on plastic cowls and capacitor housings, the Gen II uses all-metal construction throughout — providing far better protection for the motor and critical electrical components against impact, dust ingress and the daily rigours of professional use.

• Additional 3 kg weight set for increased downward pressure — The Gen II comes fitted with an extra 3 kg weight set as standard, increasing the machine's downward pressure on the pad for more effective and consistent sanding performance. This is particularly valuable on harder floor surfaces and when using abrasive screens for heavy stock removal.

• Three machines in one — sander, scrubber and stripper — Switch the vacuum motor off and the SV25 Gen II transitions from floor sander to scrubber or stripper in seconds, giving operators the flexibility to tackle multiple applications with a single machine and eliminating the cost of owning multiple units.

• Ergonomic, fully adjustable handle with safety triggers — Fully compliant with Occupational Health and Safety requirements, the height-adjustable handle with contoured grip and safety triggers makes the Gen II comfortable for operators of all heights over long working sessions — reducing fatigue and improving control across the entire job.

Why Upgrade to a Polivac 2nd Generation Floor Sander?

The SV25 Gen II is the right choice for professional floor sanding contractors who demand more from their equipment — longer gearbox life, better component protection and more downward pressure from a slow-speed machine that's been purpose-built to handle the toughest applications. The triple planetary gear drive alone represents a significant step up from the standard SV25, delivering the kind of durability that pays for itself over the life of the machine through reduced maintenance costs and less downtime.

For contractors who regularly tackle hard wearing floors, abrasive applications and heavy daily use, the Gen II's all-metal construction and additional weight set mean it keeps performing where standard machines begin to show their age. The Flexi pad holder, universal clutch and sand screen are included, meaning it's ready to work from day one.

Which Polivac Floor Sander is Right for You?

The SV25 GEN II Sandivac is the right choice when you want the durability and downward pressure of the upgraded generation at slow speed, with standard dust extraction. Here's how it sits across the full Polivac GEN II Range:

• SV25 GEN II Sandivac — Slow speed with standard dust extraction — The entry point to the Gen II range, running at 212 RPM with a triple planetary gear drive, all-metal construction and an additional 3 kg weight set for greater downward pressure and long-term durability. Choose this when you need slow-speed cutting and preparation in well-ventilated spaces and want the reliability of Gen II engineering without the step up to superior dust extraction.

• SV25 GEN II Supervac — Slow speed with superior dust extraction — The same 212 RPM Gen II slow-speed performance and triple planetary gear drive, but paired with a 400 W canister vacuum motor and by-pass dust separator for dramatically more powerful dust control. Choose this when you need the Gen II's enhanced durability and downward pressure in enclosed spaces, occupied buildings or environments with strict air quality requirements.

• SV30 GEN II Sandivac — High speed with standard dust extraction — The Gen II high-speed finishing sander, running at approximately 424 RPM with the same triple planetary gear drive and all-metal construction as the SV25 Gen II. Choose this when preparation is complete and you need fast, refined finishing results in well-ventilated spaces with the added durability of the Gen II platform.

• SV30 GEN II Supervac — High speed with superior dust extraction — The top of the Gen II range, combining the SV30 Gen II's high-speed finishing performance with a 400 W canister vacuum and by-pass dust separator for maximum dust control. The ultimate choice for contractors who need fast finishing results with superior dust extraction in the most demanding and dust-sensitive environments
