Differential Pressure System (DPS001)

We built a modular testing device to evaluate the breathability of medical-grade face masks in collaboration with Vancouver Coastal Health.


Project overview

Project name: Differential Pressure System (DPS001)
Client: Vancouver Coastal Health (VCH)
Type of project: Engineering Design, Manufacturing
Industry: Health Care Services
Project duration: December 2020 until May 2021.
Location: Victoria, BC


Rainhouse Canada is pleased to work with Vancouver Coastal Health providing a dependable and responsive service.

This project was an engineering, design, and manufacturing project in collaboration with Vancouver Coastal Health (VCH) to build a modular testing device to evaluate the breathability of medical-grade face masks. The system tests breathability by measuring the differential pressure required to draw air through a particular surface area of a medical mask at a constant flow rate.

Rainhouse worked with VCH to build this mobile test device, called the Differential Pressure System (DPS001). This device allows users to test various medical-grade face masks’ breathability during inhalation and exhalation.

Rainhouse used Vancouver Coastal Health’s design constraints in addition to the NIOSH and European Standard breathability testing procedures to design, manufacture, assemble, and test the modular mask testing station.

The result was the production of an integrated and portable Differential Pressure System currently in use by Vancouver Coastal Health to evaluate the breathability of various medical face masks.

We are grateful for the opportunity to contribute to Vancouver Coastal Health improvements and their continuous work to keep our communities safe.
