ReadyThe Honeywell Aeris Confort (Fenzy line) is dual-certified to EN 137 Type 2 and SOLAS MED, making it suitable for fire services and SOLAS-regulated marine emergency response. It uses the Zenith demand valve and is available with SX-Pro or Panoramasque facepiece options.
Dual EN 137 + SOLAS certification: when it matters
The SOLAS certification (MED/Marine Equipment Directive) means the Aeris Confort meets vessel safety requirements under IMO/SOLAS regulations in addition to EN 137 Type 2 structural firefighting standards. This is relevant for port authority fire teams, coast guard vessels, commercial vessel crews, and industrial port facilities requiring MED-compliant SCBA. A single EN 137 Type 2 certification is sufficient for land-based fire services — the SOLAS mark adds marine operational scope.
6.8L vs 6.9L carbon cylinder: the 0.1L difference
The Aeris Confort offers both 6.8L and 6.9L carbon cylinders at 300 bar. The practical difference is minimal: 6.9L × 245 (after 55 bar reserve) = 1690 L vs 6.8L × 245 = 1666 L — approximately 24 L more, or less than 1 minute at 30 L/min. The 6.9L is a manufacturer-specific production size; for planning purposes, either cylinder gives effectively the same operational duration. Select the cylinder that matches the label stamped on your actual unit.
Aeris Confort facepiece choice: SX-Pro vs Panoramasque
The SX-Pro provides a standard panoramic lens with a well-established fit profile across a wide range of facial geometries. The Panoramasque offers a wider, curved panoramic lens for broader peripheral vision. Neither facepiece choice affects cylinder capacity. Mask fit and seal quality directly affect positive pressure maintenance and actual air time — a properly fitted mask prevents bypass flow that would waste air. Fit testing with both options should be conducted before operational deployment.
No HUD or PASS on the Aeris Confort: operational requirements
The standard Aeris Confort configuration does not include integrated HUD or PASS. Standalone PASS devices should be used to meet EN 137 Type 2 operational requirements. Air management relies on the mechanical pressure gauge — regular gauge checks and clear communication of air status to the entry team and IC are essential. For marine applications, standalone PASS integration with vessel alarm systems may be specified in vessel safety management plans.
FAQ
Honeywell SCBA Air Time Calculator (Survivair / Fenzy Planning Estimate)
Different regions use different Honeywell product families (Survivair, Fenzy, and related lines), but the air math stays the same. This Honeywell SCBA Air Time Calculator estimates remaining time using cylinder water volume, usable pressure after reserve, and RMV (L/min). Use it for training and pre-plans — not for compliance or official documentation.
Honeywell Fenzy (EU) vs Honeywell Survivair / TITAN (US): two separate lines
Honeywell's SCBA portfolio includes the Fenzy line (originating from the French manufacturer acquired by Honeywell), sold in European and EN 137 markets as the Aeris Confort and related models, and the TITAN series, which is Honeywell's NFPA 1981 platform for North American fire services. These are distinct systems: cylinder connectors, pressure ratings (300 bar EN vs 4500 psi NFPA), and electronics are not interchangeable. The Aeris Confort uses the Zenith demand valve; the TITAN uses a different regulator design. Select the model matching your actual unit.
Honeywell Aeris Confort: EN 137 + SOLAS certification
The Aeris Confort is certified to both EN 137 Type 2 and SOLAS (Safety of Life at Sea), making it dual-qualified for fire services and marine emergency response. This is relatively unusual among SCBA and makes the Aeris Confort useful in port authority, coast guard, and vessel firefighting contexts where SOLAS compliance is required alongside structural firefighting capability. Air time calculation is the same — water volume × usable pressure ÷ RMV — but users should be aware of which certification scope applies to their operational context.
Aeris Confort facepiece options: SX-Pro vs Panoramasque
The Honeywell Aeris Confort is available with the SX-Pro facepiece (standard panoramic lens) and the Panoramasque (wider field of view). Facepiece selection affects ergonomics, communication, and thermal exposure, but does not affect cylinder capacity or air consumption. Mask fit and seal are critical to actual air time — a poor-fitting mask allows positive-pressure bypass, which effectively wastes air and reduces protection.
Honeywell TITAN: NFPA 1981 and digital dashboard
The Honeywell TITAN is Honeywell's current US flagship for NFPA markets. It includes a digital pressure display integrated into the harness frame and supports 4500 psi (310 bar) cylinder options. A digital dashboard integration option allows remote monitoring of crew air status. The TITAN is one of the heavier units at 4.9 kg without cylinder — departments moving from lighter units should factor increased wearer fatigue and potentially increased RMV for extended entries.
Using this calculator for non-Honeywell-branded Fenzy units
Some departments operate SCBA units originally sold as Fenzy brand before the Honeywell acquisition — these older units use the same fundamental cylinder and pressure standards as current Aeris Confort units if certified to EN 137 Type 2 at 300 bar. The calculation method applies equally. However, older 200 bar Fenzy units (if in service) would require manual entry of the correct service pressure rather than relying on the presets.

Notes & Safety
This is an estimate based on the values you enter. Real-world air consumption changes with workload, stress, temperature, mask seal, leaks, and individual physiology. Always follow your SOPs and monitor your pressure gauge continuously.
