Keep Them Working.
In mining, quarrying, construction, and demolition, heavy equipment operators are exposed to respirable dust every shift. Much of that dust contains fine silica particles — and silica causes irreversible lung disease. Standard OEM cabin ventilation offers minimal protection against sub-micron particles.
A HEPA cabin pressurisation system changes that entirely. It draws external air through hospital-grade HEPA filters, maintains positive pressure inside the cabin to prevent dust ingress through gaps and seals, and continuously monitors air quality — so you know your operators are protected every shift.
⚠ Health Warning. Respirable silica dust causes silicosis — an incurable, progressive lung disease. There is no safe level of exposure. Australian WHS regulations require employers to eliminate or minimise silica dust exposure so far as reasonably practicable.

Simple in Concept. Critical in Practice.
Four jobs. Done right, the result is a sealed, filtered, monitored cabin that protects your operator every shift.
Filter External Air
Ambient air drawn through a HEPA H14 filter — capturing 99.995% of particles at 0.3 microns, including fine respirable silica.
Pressurise the Cabin
Clean filtered air supplied at a rate maintaining positive pressure — typically 20–200 Pa above ambient — preventing dust entering through gaps and seals.
Monitor in Real Time
The BreatheSafe InPress controller displays cabin pressure and CO₂ levels live. Audible and visual alarms trigger if readings fall outside safe range.
Service & Maintain
Setpoint services systems on-site across SA with all parts stocked locally. Full service documentation provided for compliance records.
ISO 23875 compliant. BreatheSafe systems are engineered to exceed ISO 23875 — the international standard for operator cabin air quality in mining and heavy industry. Many Australian mine sites now require ISO 23875 compliance as a condition of entry.
a Compliance Box.
Fleet managers who install HEPA pressurisation systems report benefits well beyond health and safety compliance.
Operator Health
Eliminate silica dust exposure and protect your operators from long-term lung disease. Healthy operators work longer and take fewer sick days.
Productivity
Operators in clean, pressurised cabins experience less fatigue and better concentration — contributing to better performance over a full shift.
Reduced Liability
Demonstrates due diligence under WHS obligations and protects your business in the event of a health incident or regulatory audit.
Less Machine Downtime
Dust ingress causes premature failure in cabin electronics and HVAC systems. A pressurised cabin dramatically reduces dust load on internal components.
Component Longevity
HVAC systems, monitors, and electrical connectors last longer in a clean cabin — measurable reductions in component replacement costs over time.
Site Access
Major mine sites increasingly require HEPA-pressurised cabins as a condition of entry. Don't be excluded from high-value contracts.
Are you the only authorised BreatheSafe installer in Adelaide?
Yes. Setpoint is the sole authorised BreatheSafe installer based in Adelaide, South Australia. We hold the training, accreditation, and supply arrangements to install and service BreatheSafe systems correctly — and stock all parts and filters locally for fast turnaround.
What is the difference between a HEPA filter and a standard cabin air filter?
Standard OEM cabin filters capture larger particles but offer minimal protection against fine respirable dust below 10 microns. HEPA H14 filters capture 99.995% of particles at 0.3 microns — including the sub-micron silica particles most dangerous to lung health. A pressurisation system also adds positive cabin pressure to prevent unfiltered air entering through gaps, which a filter alone cannot achieve.
How long does an installation take and do you come to site?
Yes — we come to you, anywhere in SA. No workshop drop-off required. Most installations are completed in a single day on-site, typically 4–8 hours depending on machine model. We schedule around your production windows to minimise downtime.
How often do filters need replacing?
In heavy dust environments, HEPA filters typically need replacing every 1,000–2,000 operating hours. Pre-filters are replaced more frequently — often every 250–500 hours depending on dust load. Because we stock all filters locally in SA, we can turn around replacements quickly without waiting on interstate freight.
Can you service our existing pressurisation systems?
Yes. Setpoint services existing HEPA pressurisation systems across SA — filter replacement, pressure testing, InPress controller calibration, and fault diagnosis. With parts stocked locally, we can often complete the service in a single on-site visit.
Authorised Installer
Protecting operators from respirable dust isn't just a compliance requirement — it's the right thing to do. Setpoint is Adelaide's sole authorised BreatheSafe installer, with all parts and filters stocked locally in SA. We supply, install, and service HEPA cabin pressurisation systems on-site, anywhere in the state — so your operators are protected and your machines keep running.
