Diluter system


The SCS-Diluter is a stand-alone general filtration system, developed to reduce and control the background concentration of welding fumes in a workshop.

  • Low installation cost
  • Flexible
  • Efficient filtration

The SCS-Diluter is a smart solution without ductwork

In some cases source extraction and hoods are not an option, for example if metalwork pieces are too big to be covered by extraction arms, as in the ship-building and transport industry, or if welders constantly move in between positions. Plymovent has therefore developed a general filtration system that can control welding fumes in large facilities: the SCS-Diluter.

Recommended for

  • The SCS-Diluter has been specially designed for light to medium welding processes.


  • Low installation cost
  • Flexible
  • Efficient filtration

This solution can be used in large workshops with various welding processes, changing activities, crane transportation and locations where ductwork is difficult to install. The result: reducing the concentration of fumes to lower levels, giving a cleaner working environment!

Flexible solution

Installing the Diluter system is easy as you do not need any ductwork. It does not only save ductwork costs, it is also a very flexible solution for facilities with many welding processes, changing locations constantly.

Minor investment maximum result

The Diluter system consists of three main components: the SCS-filter unit, a fan and the Diluter itself. The Diluter is an air circulation unit with six multidirectional outlet nozzles. The unit re-circulates the cleaned air into the workshop by means of the outlet nozzles.

The nozzles can be rotated to optimise air distribution. The airflows from the nozzles can be controlled individually making the system unique. Positioning the nozzles directly towards the welding fume layer gives the best result (usually between 13 and 20 feet (4 and 6 meters)). The main benefit is the relatively small investment for controlling welding fumes in your plant.

Two versions of filter controls

The SCS-Diluter will be available with the new filter controls of Plymovent; the ControlPro and the ControlGo.

SCS-Diluter PRO

The SCS-Diluter PRO is fitted with the ControlPro. This version has a control with an intuitive touchscreen interface that shows at a glance how the system is performing, what the system is doing now, will do next and how to keep it in shape. An extensive and very accessible menu allows full adaptability in an easy way. ControlPro uses ethernet communication for a wide variety of connectivity options. ControlPro is the control that meets the full needs of the professional user: Simple, Insight, Connected.

If your filters are steered by ControlPro control systems, Plymovent gives the option to extend it with ControlPro Connect. This is an advanced web portal that gives you the power to monitor, manage and control any number of filters at a glance from your PC, tablet or smartphone. This version uses the FCC-150 filter cartridge and has an operational airflow of (max.) 5,297 CFM (9000 m3/h)

SCS-Diluter GO

The SCS-Diluter GO has integrated control unit the ControlGo. The ControlGo is built on the same platform as the ControlPro, offering the same performance, but with preset configurations for the user with basic needs. The SCS-Diluter GO uses push buttons and indicator lights for simple interaction and meets the basic needs of any user. This version uses the FCC-150 filter cartridge and has an operational airflow of (max.) 5,297 CFM (9000 m3/h)
