What makes it work

Built for residential and small commercial floors

Lavina L20S7 electric floor grinder, front view
The 20N Elite's replacement
Lavina no longer builds the 20N Elite. The 20 S7 takes its place in the electric line with the same 20 inch path and three 9 inch tool holders on a redesigned S7 frame.
Sealed, dust-proof head
The grinding head is sealed against slurry and dust, with a redesigned chain-driven planetary and upgraded shafts, seals and bearings, for a longer service life and less maintenance.
Wide speed range
The tool holders run 400 to 1100 rpm: low for metal bonds and PCDs on coatings and glue, high for polishing.
New frame, easier tool changes
Integrated weights switch position faster, the frame opens up for tool changes, and rubber bushings at the head mounts cut vibration at the handle.

Works with

Pairs with a Lavina electric dust extractor sized to the 20 inch head, plus Latux metal-bond and PCD tooling on the quick-change plates. Use blue PCDs and carbide scrapers on the left-rotating heads. Run the grinder, extractor, and tooling together for clean, low-dust prep and polishing indoors.

Looking for the 20N Elite?

The Lavina 20N Elite is no longer manufactured, and the 20 S7 is Lavina's replacement for it. The 20N Elite specs are still here for reference and for service on machines already in the field.

Does the 20 S7 replace the 20N Elite?

Yes. Lavina no longer manufactures the 20N Elite and lists the 20 S7 (L20S7) as its replacement in the electric line.

Single or three phase?

Either. It runs on 1 or 3 phase, 200 to 240 V at 30 A, so it fits most shop and job-site power.

How much grinding pressure does it apply?

211 to 287 pounds, with the tool holders turning 400 to 1100 rpm.

What dust extractor should I pair with it?

A Lavina electric extractor sized to the 20 inch head. Your Latux rep can match one to your jobs and your power.

How do I buy it, and what about freight?

The 20 S7 is sold by quote. Call or message your Latux rep for current price, freight, and lead time. The MSRP shown is for reference.
