VARIBOX FC 800 NS4 extractor tube Viton

The VARIBOX FC 800 NS4 Extractor Tube Viton is designed for applications where chemicals need to be dosed accurately and safely from the VARIBOX FC 800. Rather than focusing on rapid transfer, the NS4 system is specifically developed for fine dosing, making it suitable for processes that require a controlled supply of chemical.

The extractor tube reaches the lowest point of the inner container and connects to a corresponding NS4 coupler at the top. This allows the chemical to be pumped directly from the VARIBOX into the dosing installation without opening the container during normal operation.

By combining fine dosing with closed transfer, the NS4 system provides a practical connection between reusable chemical packaging and your production process.

Designed Around Controlled Dosing

Industrial processes do not always need high flow rates. Water treatment, process chemistry and other dosing applications can require relatively small quantities of chemical to be introduced in a controlled manner.

The NS4 system has been developed specifically for this type of application. Instead of rapidly emptying the FC 800, it provides a controlled route from the chemical inside the container to the connected dosing equipment.

This makes the VARIBOX FC 800 suitable as a direct supply source for applications where consistent chemical dosing is more important than high-volume transfer.

The chemical remains inside a closed system from the VARIBOX to the connected installation, supporting both process control and safer handling.

Keep the VARIBOX Closed During Dispensing

Opening chemical packaging during normal dispensing can increase the possibility of operator contact with the product and exposure to fumes.

The NS4 system provides a different approach.

A matching NS4 coupler connects directly to the top of the extractor tube. Once connected, the chemical can be pumped from the VARIBOX through the closed dispensing connection. There is no need to open the VARIBOX to access the product during normal use.

Keeping the container closed helps prevent chemicals and fumes from escaping, providing an important safety advantage when handling demanding liquid chemicals.

From the Lowest Point Directly to Your Process

The NS4 extractor tube extends all the way to the lowest point of the FC 800 inner container.

This allows the dosing system to draw product from the bottom of the VARIBOX while maintaining the connection at the top of the container.

For industrial users, this creates a convenient setup: the VARIBOX can remain closed while the connected pump extracts chemical through the dedicated NS4 system.

Efficient extraction also helps make better use of the chemical delivered in each VARIBOX and limits the amount of product that remains inaccessible at the end of the dispensing cycle.

Standard Return Connection for Dosing Systems

Certain dosing installations require a return connection in addition to the main extraction line.

The NS4 extractor tube includes a return connection as a standard feature at the top of the system.

This allows dosing installations that require a return route to connect directly to the NS4 system without requiring an additional opening in the VARIBOX.

Bringing extraction and return functionality together at the top of the container makes NS4 particularly suitable for specialised industrial dosing installations.

Viton Configuration for the FC 800

This version of the NS4 extractor tube is the Viton configuration developed for the VARIBOX FC 800.

It is manufactured using Viton, PE, PP, TPV and Hastelloy, providing a dedicated material configuration for chemical applications requiring the Viton version of the NS4 system.

The extractor tube must be combined with the corresponding NS4 Viton coupler to create the intended connection between the VARIBOX and dosing equipment.

Chemical compatibility should always be checked for the specific substance being handled. Concentration, temperature and process conditions can all influence the suitability of materials in a chemical dispensing system.

Connect with the Corresponding NS4 Viton Coupler

The extractor tube forms the container side of the NS4 dispensing system. To connect it to external equipment, a corresponding NS4 Viton coupler is required.

VARIBOX offers both NS4 body and insert coupler configurations in Viton. These components are designed to establish a liquid-tight connection with the NS4 extractor tube.

This modular approach allows the connection to be adapted to the requirements of the dosing installation while maintaining the NS4 interface at the VARIBOX.

Using original matching components helps ensure that the individual parts are designed to function together as one dispensing system.

Built for Reusable Chemical Supply

The NS4 Extractor Tube complements the wider VARIBOX philosophy of Safer, Reusable and Sustainable chemical packaging.

Safer

Closed dispensing helps separate operators from the chemical being handled. Because the FC 800 does not need to be opened during normal extraction, chemicals and fumes can remain contained within the dispensing route.

Reusable

The VARIBOX FC 800 is designed for repeated industrial use. Dedicated components such as the NS4 extractor tube can be maintained and replaced individually when required, supporting the long-term operation of the complete packaging system.

Sustainable

Reusable packaging helps reduce dependence on single-use chemical containers. Combining this with a serviceable dispensing system supports longer product life and more efficient use of packaging components.

Controlled extraction from the lowest point of the inner container also helps make effective use of the chemical inside each VARIBOX.

Fine Dosing Without Opening the Container

The VARIBOX FC 800 NS4 Extractor Tube Viton combines the practical capacity of the FC 800 with a dispensing solution specifically developed for fine dosing.

Its closed extraction principle helps keep chemicals and fumes contained, while the standard return connection supports integration with specialised dosing installations. The Viton configuration provides a dedicated option for applications requiring this material combination.

From the lowest point of the inner container to the connected dosing equipment, NS4 creates a controlled route for transferring chemical directly into your process.
