RadialSHIELD®
Air Filters
Sy-Klone air quality systems come paired with our patented RadialSHIELD® filtration technology to deliver powerful protection and reliable performance.
Our advanced filters are engineered to deliver high-efficiency performance across a wide range of particle sizes—from the smallest diesel particulate matter (DPM) and combustion particles to larger contaminants such as silica dust and asbestos fibers.
Engineered for durability with 100% seal technology, each filter housing is built to last while delivering reliable, consistent protection. This robust construction prevents dust bypass and optimizes filter life—reducing cost of ownership, supporting compliance, protecting operators, and enhancing equipment reliability in demanding environments.
What you can't see can harm you.
Not all HEPA filters are created equal.
RadialSHIELD® HEPA filtration media has been independently tested to achieve 99.95% efficiency at 62 nanometers MPPS, capturing ultrafine particles such as diesel exhaust and airborne viruses, the smallest particles.
- 99.99% efficiency @ 0.3 µm
- 100% seal integrity tested up to 10,000 kPa
- Self-cleaning membrane filters contaminants without collapsing or caking, extending filter life up to 10x
- Outperforms traditional filters every time
Filter Type Comparison
MERV 16
Highest MERV Rating
Substantially improves air quality on job sites. When standards compliance is not the primary objective, this filter is a high-performance, cost-effective solution.
- High-efficiency, lowest restriction RESPA® filter
- Filter efficiency of ≥95% on average of 0.3 to 1.0 micron
EPA
Efficient Particulate Air
Applicable to most job sites and high-debris applications, is designed to arrest small airborne contaminants and meet timed dust decay rates.
- Higher-efficiency, lower-restriction RESPA® filter
- Filter efficiency of 99% at 0.3 micron
- ISO 23875 compliant
HEPA
High Efficiency Particulate Air
Designed to arrest the smallest airborne contaminants and respirable particulate, meant for hazardous conditions that require top-grade filtration.
- Highest-efficiency RESPA® filter
- Filter efficiency of 99.99% at 0.3 micron
- ISO 23875 compliant
Fresh Air Filters
Clean, safe air for cabs and enclosures starts with high-performance filters. Our MERV 16, EPA, HEPA, Odor + HEPA, Gas + HEPA, and Ammonia + HEPA options fit all RESPA® CF2 and CFX2 systems. Our EPA and HEPA filters exceed ISO 23875 filter efficiency requirements.
Sy-Klone offers Gas + HEPA ABEK1 filters to provide broad-spectrum protection against harmful industrial gases, chemical vapors, and hazardous airborne contaminants—enhancing operator safety in demanding environments.
Gas Filtration Classification (ABEK + Hg)
- A1 – Protection against organic gases and vapors (e.g., hydrocarbons, solvents)
- B1 – Protection against inorganic gases and vapors (e.g., chlorine, hydrogen sulfide)
- E1 – Protection against acid gases (e.g., sulfur dioxide)
- K1 – Protection against ammonia and ammonia derivatives
- Hg – Protection against mercury vapor
