Item Number: R312
Condition: Used
Availability: Limited
Warranty: 3 Years

This item fits model D4C, D3C, D3A, D2A, D2, and D. On the model D4C and D3C, you must have the original R1976 spider that came standard for this to fit correctly.

On March 28th 2002, Rexair discontinued production on this item and also the matching R1976 spider. We realize that many people still have the model D4C and D3C Rainbow system, so we offer used as a solution.

If you need to replace both separator and spider, then you would order item numbers R4100, R4101, and H555. These three items are a direct replacement and also an improvement.

The separator separates the air from the water. The water is thrown back into the water pan and it allows clean air to go up through the motor and out the exhaust. Be sure to take off and clean periodically as it can become clogged with dirt and will reduce your performance.

If you have a plastic separator that does not have a metal band around the outside edge, at some point the separator may break into pieces during use. The metal band was added to prevent this issue from occurring.

This nut fits the older style R312 separator. Be sure to look at the image closely as the other types of separator nuts have a flat base and do not work correctly with the R312 plastic separator. If you have a metal separator, then please order an H555 that has the flat base.

The separator is one of the most important parts on the Rainbow cleaning system. It throws the water back into the water pan and allows clean water washed air to travel up through the motor and out the exhaust. Be sure to take off and clean as it can become clogged with dirt and debris.

If your model is the D4C SE (Special Edition) with the R4101 spider, then this is the current revision. If you have a D4C or D3C, then you would also need to order the R4101 and H555.

This item has had several upgrades over the years since it was first introduced with the Special Edition model D4C Rainbow.

It was originally a gray color matching the original separator. Then it changed to a yellow-tan color that matches the current R4100 separator. Then if finally was redesigned from the cone shape to what it looks like today. It was also at that time when it became black in color. No matter which version you have, this is a direct factory OEM replacement.

The spider sets under the separator and works directly with the separator. This spider and the R4100 separator was one of the upgrades that was done when the D4C Special Edition (SE) was introduced in 1990.

This has to be purchased as a kit if you are replacing an original R1976 spider from a model D4C or D3C Rainbow. If you have an R1976 currently, then order an R4100, R4101 and H555.

Replacement screw (bolt) for the model D3A and D2 Rainbow and is designed to match the plastic separator that has a beveled edge around the center hole. This bolt under the head is chamfered to sit in this beveled pocket.

Works with the female type armatures found on the above original motors. If your motor has male threads on the end of the armature, then this is NOT the correct part. You need to order an H524 or an H555 separator nut.
