Sy-Klone Cab Air Quality Systems

1. Fresh air and debris are pulled into the powered pre-cleaner/filter/pressurizer (RESPA-CF2).
2. Debris is separated from the airflow and ejected from via patented technology.
3. Cleaned and filtered air is delivered to the machine’s HVAC unit without added restriction by the powered RESPA unit. This creates positive pressure, which prevents dust from ingressing into the cab.
4. Clean, filtered, and conditioned air flows through the cab.
5. Monitor alerts the operator to the loss of positive pressure in the cab and when to change the RESPA filter.
6. High-efficiency recirculation filtration (Powered RESPA-CFX and PFX) continuously removes dust from the cab, minimizing settled dust accumulation. Clean, filtered air flows back to the HVAC plenum.

• Exceeds AS/NZS ISO 23875 (Australian & Global Standard for cab air quality) and RS20 (Recognised Standard for cab air quality) engineering control requirements when configured with EPA or HEPA filtration and the RESPA Advisor+ CO₂ + Pressure Monitor.
• Air quality control systems for all operator enclosures, performance requirements, and test methods pave the way to ensuring all mobile machinery operators’ safety. Sy-Klone products improve air quality and reduce occupational exposure to meet cab quality standards.
• Meets engineering controls criteria specified by OSHA Silica Rules, including precleaning, MERV 16 or better filtration, positive pressurization, and settled dust removal.
• Protect operator health and life longevity
• Dramatically extend filter life
• Increase operator comfort and productivity
• Decrease operational cost
• Reduce environmental contamination and deterioration of cab electronics
• Endorsed by ISEEE as a Best Practice Component

• Mobile Machinery Assets – Operator Cabs
• Concrete Batch Plants/testing facilities
• Demolition

Published in February 2021 and updated in 2022, ISO 23875 is a new international standard that unifies the design, testing, operation, and maintenance of air quality control systems for heavy machinery cabs and other operator enclosures, particularly in the mining industry. Adherence to the requirements and testing methods set out in the standard supports the safety of machine users, improves productivity, promotes operator alertness, and enables companies to reach exposure reduction goals.

• Reduced exposure to respirable particulate
• Reduced exposure to CO2
• Improved operator safety, comfort, and moral–supporting exposure reduction goals, health and safety efforts, and recruitment/retention
• Improved machine uptime and lower operating costs through meeting defined maintenance intervals

1. Defined CO₂ Levels
   First alarm threshold: Ambient CO₂ level plus 400 parts per million (PPM).
   Second CO₂ alarm threshold: 2,500 PPM.
2. Defined Fresh & Recirculation System Efficiency
   Maximum respirable particulate matter concentration less than 25 micrograms per cubic meter of air at start and end of decay test (maximum 120-second decay time).
3. Increased Filter Efficiency Requirements
   Updated in June 2022: Filtration that exceeds 94% efficiency at 0.3 microns is recommended. Filters must pass the required intake air leakage and particle decay tests.
4. Defined Pressurization Requirements
   Operator enclosures must maintain a minimum pressure of 20 Pa with key on and HVAC blower turned off.
5. Defined, Real-Time Monitoring Requirements
   Monitor must include an audible alarm for CO2 and pressurization to alert the operator when levels exceed the permissible pressure and CO₂ thresholds.
