"VS" Series - Modular Catch Cans

Introduction

A few years ago, we introduced a new catch can design that is quite different from anything else available. The design is based on proven coalescence and gas separation principles, and takes advantage of a special filter material that is designed specifically to remove oil aerosols down to 5 microns or less, while maintaining a very low pressure drop. After tens of thousands of miles logged on hundreds of different vehicles, these cans continue to work as well or even better than expected in a wide range of applications.

Based on the success of the original design, we are now offering the "VS" series of catch cans. While maintaining the performance of the original cans, the new cans offer more flexibility and options, and can be more specifically tailored to individual needs. Like the original, these cans are designed to be tied to a source of vacuum (typically a turbo inlet) for best performance; but they can also now be configured to operate as a traditional open-breather type of can if desired. This is possible due to a new modular design, which allows the filter to be removed and replaced with different filter types and/or connections.

Although different configurations are available, all of these cans use the same basic design for the inlet (or outlet) filter. The standard filter element is a custom manufactured fiber-resin material, capable of removing particles down to 5 microns or lower. This element is capped and then attached to an aluminum plate, which is assembled to the can body with machine screws and sealed with a Buna-N gasket.

In addition, the dual-chambered cans (pictured at left; see "VS3" below) utilize a bonded aluminum mesh material on the inlets, to provide coarse filtration and liquid separation as the flow first enters the can.

We currently offer three different styles of this catch can, each with their own unique characteristics and configuration options. The following sections will describe each style in detail, along with all of the options available.

All of the VS series cans come with an open 1/4" NPT female drain port, but for an addtional $8 we can also include a 90* positive-lock brass drain valve.

Note: If room for the valve is tight, you can put an elbow/barb nipple on the can and mount the valve remotely using a custom bracket or zip tie.

For the VS3 (and VS1 cans that are 6" tall), the standard round sight glass can be replaced with a 3" sight tube for an additional charge. This sight tube offers more visibility than the round glass, at the expense of adding a bit of weight.

Note: The outer guard can be removed for even more visibility if desired. Carefully remove the bolts and slip the guard off, and then re-insert the bolts with the o-rings between the bolt head and body of the tube.

VS1

The VS1 is a small, single inlet/single outlet can with a removable filter module on top. It is ideal for filtering the line between the PCV valve and intake manifold, which normally sees a fairly low amount of airflow and pressure, or for any application where a simple, small capacity can would be a good choice.

The VS1 dimensions are 2-1/2" x 2-1/2" x 4" tall, and it comes with male -8AN inlet and outlet fittings, a round sight window, and a welded mounting bracket. The inlet/outlet size can be changed if desired, and the height can be changed to 6 inches.

With the standard configuration of the VS1, the filter module on top is the inlet, and the baffled port on the right side is the outlet. However, if the filter module is replaced with an external breather and the inlet line moved to the side, it will function as a traditional open, non-sealed catch can.

The outlet, sight window, and bracket can usually be relocated to other places on the can's body if necessary, although there may be a small additional charge.

The base price of the standard VS1 catch can as shown above is $140.00, which inludes USPS priority shipping to the continental US. Prices will vary depending on special shipping requirements, or with any options as described below.

VS2

The VS2 is the new and improved version of the original dual-inlet can. The top inlets are part of a dual-filter module that can be removed for inspection or cleaning should the need ever arise. The outlet is a single baffled port on the can's side.

The VS2 dimensions are 3" x 5" x 6" tall, and it comes with male -8AN inlets, a -10AN outlet, a round sight window, and a welded mounting bracket. The inlet/outlet size can be changed if desired, and dual outlet ports can be located on the front rather than a single outlet on the side as an option. 

NOTE: The VS2 is designed for applications where engine blow-by is relatively dry, on stock to mild engines. For heavily modified engines, ethanol fuels, and more versatility, the VS3 shown below is recommended.

The picture at right shows the standard VS2 can. The outlet, sight window, and bracket can usually be moved to other sides of the can's body if necessary, although there may be a small additional charge.

With the standard configuration of the VS2, the dual filter modules on top are the inlets, and the baffled port on the right side is the outlet. However, if the filter module is replaced with external breathers and dual ports are added to the front (which become the inlets), it will function as a traditional open, non-sealed catch can.

The picture at left shows a VS2 with two -10AN inlets on the front, and a dual breather module on top instead of the standard internal filters.

The base price of the standard VS2 catch can as shown above is $200.00, which inludes USPS priority shipping to the continental US. Prices will vary depending on special shipping requirements, or with any options as described below.

VS3 This is our most popular and versatile can. It works well with almost any setup, and can be more easily modified for different configurations than the VS2. The VS3 is a dual-chambered design that has two fixed inlets, and a modular filtered outlet. Air enters a chamber on the left that is filled with a coarse, bonded aluminum media which removes the majority of suspended liquids and larger particles, and then flows out of the can through the filter on the outlet which further filters the air to remove smaller particles. Although the VS3 provides slightly less filtering than the VS2, the dual-chamber design makes it a good choice for setups that have a lot of blowby with suspended liquids, or for those running ethanol-blended fuels in colder climates.  The VS3 dimensions are 3" x 5" x 6" tall, and it comes with male -8AN inlets, a -10AN outlet, a round sight window, and a welded mounting bracket.  The picture at right shows the standard VS3 can. The sight window and bracket can usually be relocated to other places on the can's body if necessary, although there may be a small additional charge. The inlet/outlet size can be changed if desired, and some variation of the inlet position is possible...but the inlets and outlets must remain on the top plate. Like the VS1 and VS2, the filter module can be replaced with an external breather, and it will function as a traditional open, non-sealed catch can. The picture at left shows a VS3 with two -10AN inlets, a breather module, and the optional 3" sight tube in place of the standard round sight window.
