Frequently Asked Questions

Where are the Negative Pressure Units manufactured?

The AMS and SMH Negative Pressure Units are manufactured in the UK by SMH Products. Allens Industrial is the exclusive distribution partner for SMH products in Australia.

What is a Negative Pressure Unit?

A Negative Pressure Unit (NPU) is designed to create negative pressure inside an enclosure to prevent the escape of airborne particles. Air is drawn into the unit by a powerful motor and filtered through a series of increasingly efficient filters.

What size NPU do I need?

This depends on the size of the enclosure and other job-specific factors. Please feel free to contact us with any requirements.

What does DOP stand for?

DOP stands for Dispersed Oil Particulate. The test is performed to ensure there are no leaks in the HEPA filter or the internal seals of the machine, maintaining the required 99.995% filtration efficiency.

Do the Negative Pressure Units come with a DOP certificate?

Yes, all Negative Pressure Units sold through Allens Industrial Products are individually DOP tested and come with a certificate at the time of purchase.

How do I monitor negative air pressure of approximately -12 Pa within the enclosed area?

We recommend the Omniguard Differential Pressure Monitor for real-time monitoring and easy data transfer.

What is the airflow of the Negative Pressure Unit?

The AMS 1500 NPU produces an approximate nominal airflow of 2200m³/hr.

Are the Negative Pressure Units kept in stock?

Yes, we carry a range of Negative Pressure Units in stock at our Brisbane, Sydney, and Melbourne warehouses. Please feel free to contact us for availability.
