What makes it work

Built for big commercial floors

Lavina L31RS7 floor grinder with its remote control
The 32 Elite's replacement
Lavina no longer builds the 32 Elite. The 31R S7 takes its place in the remote-controlled line with the same 20 hp motor and 13.2 inch tool holders on a sealed S7 head.
Remote control
A handheld remote with a 4.3 inch color display drives the grinder and sets rpm, rotation and swing correction, while the screen shows voltage, load, hours and maintenance alerts. It also runs in manual mode.
Sealed, dust-proof head
Upgraded internals and planetary drive are sealed against slurry and dust, for a longer service life and less maintenance between jobs.
Tunable pressure
471 to 767 lb of grinding pressure, or 834 lb with the optional extra weight (#A114), for aggressive removal through a controlled polish.

Does the 31R S7 replace the 32 Elite?

Yes. Lavina no longer manufactures the 32 Elite (L3213REB) and lists the 31R S7 (L31RS7) as its replacement.

What power does it need?

Three phase, 200 to 240 V at 60 A, or the high-voltage version at 400 to 480 V, 32 A.

How much grinding pressure does it apply?

471 to 767 pounds, or 834 pounds with the optional extra weight, with the tool holders turning 400 to 650 rpm.

What dust extractor should I pair with it?

A Lavina V32E electric or V32GE propane extractor keeps up with the 31 inch head and captures the silica it produces.

How do I buy it, and what about freight?

The 31R S7 is sold by quote. Call or message your Latux rep for current price, freight, and lead time. The MSRP shown is for reference.
