The Helix VR 2.3 is the variable-ratio machine, 1:1 to 1:4, at 3300 psi. The Helix FR is a fixed true 1:1 dual-pump unit with viscosity calibration. The Helix LP is a 1:1 low-pressure spray foam system rated at 120 psi. FR and VR share many parts; LP parts are separate.
Titan sells three Helix families, and parts listings use the names loosely: Helix VR, Helix FR, Helix FR28, Helix LP. None of them is a paint or fine finish sprayer. All three are two-part proportioners, and the first job when you shop for a part is to be certain which family your machine is. This guide sets out what we can verify about each.

Helix VR 2.3: the variable-ratio machine
The VR is the one to look at when a coating is not 1:1. It covers any ratio from 1:1 to 1:4, runs electronically controlled dual pumps that keep in communication, and carries Titan's Smart Select controller. MCC lists the US version at 230 V, 3 phase, 70 A, and the weight at 285 lbs. Wagner Australia also gives the weight and the 3 phase, 70 A supply. Titan describes the VR as 30 percent lighter than comparable proportioners.
Helix FR and FR28: fixed ratio
The FR holds a true 1:1 ratio and uses viscosity calibration to do it. Its heater is an aluminum mass heater with a wrap-around design and a dwell time of over 30 seconds, and it is modular from 3 kW to 18 kW. Titan describes an EasyOut fluid section that keeps the pump isolated from the environment, fixed wipers that clean the piston rod, and priming and flushing that can be done independently. The FR28 version is listed for spray polyurethane foam as well as polyurea and polyaspartics.
We do not list a pressure or an output for the FR, because we could not verify either one. If you need them, they are in the Helix FR manual on our manuals page.
Helix LP: low-pressure spray foam
The LP is a different kind of machine. It is a 1:1 low-pressure spray foam proportioner, rated at 120 psi, on a 230 V, 30 A supply with a 1 HP motor. MCC lists a 4600 W hose and a 6900 W system, and a 15 lbs per minute output. The part number 0138040 is listed with a 200 ft hose. It has an in-hose heating element and independent priming and flushing, and it delivers A and B equally.
Parts overlap and differences
The site has no Helix diagram pages, so parts are individual listings, and fitment is whatever the catalog's fits field says. Many VR parts say Helix FR and Helix VR together. LP parts are separate. A few examples:
Examples of what the fits fields say
A shared fits field is a starting point, not a promise that a part is interchangeable on your unit, and we do not claim cross-fit. Confirm by phone before ordering anything for a machine whose family you are not sure of.
How to confirm your model
- Read the data plate on the machine for the model name and serial number.
- Match the plate to the family above: ratio range, power supply and what it is used for.
- Download the manual for your family from our manuals page, which carries the Helix VR, FR, LP and hose manuals.
- Browse the Titan parts list or the sprayer parts category and check each listing's fits field.
- If anything is unclear, call (713) 931-0006 with the model and serial number.

The Short Version
VR is variable ratio, FR is fixed 1:1, and LP is low-pressure spray foam. Many parts list FR and VR together, LP parts are separate, and no listing is a promise of cross-fit. Check the data plate and call us before you order.
