Spasciani RN / MK2 SCBA Air Time Calculator

The Spasciani RN/MK2 is an Italian-manufactured EN 137 Type 2 structural firefighting SCBA with CE 0426 certification, available in two connector configurations (Type A standard screw and Type BN proprietary snap) and three cylinder sizes.

Type A vs BN connector: cross-fleet compatibility implications

The Type A connector uses the EN 148-3 standard screw thread, which is the most common facepiece-to-demand valve connection in European SCBA. A Type A Spasciani demand valve is compatible with EN 148-3 facepieces from other manufacturers — relevant for departments that operate mixed fleets or need backup mask compatibility. The Type BN uses Spasciani's proprietary snap connection — faster to don and remove, but only compatible with BN-designated facepieces. When procuring or expanding a fleet with RN/MK2 units, confirm which connector type existing facepieces use to maintain interoperability.

RN/MK2 cylinder selection: 6.0L steel vs 6.8L vs 9.0L composite

Three cylinder options provide different air capacity tiers. 6.0L steel at 300 bar (50 bar reserve): 6.0 × 250 = 1500 L ÷ 60 L/min = 25.0 min. 6.8L composite at 300 bar (55 bar reserve): 6.8 × 245 = 1666 L ÷ 60 = 27.8 min. 9.0L composite (55 bar reserve): 9.0 × 245 = 2205 L ÷ 60 = 36.8 min. The 9.0L composite option provides approximately 47% more air time than the 6.0L steel — significant for long-duration interior operations.

CE 0426 notified body: what it confirms

CE 0426 is the marking from the notified body that performed the conformity assessment for the RN/MK2 against EN 137 Type 2. The notified body number (0426) identifies which approved EU testing laboratory certified the product. This confirms the unit has undergone third-party testing, not just manufacturer self-certification. For procurement purposes, CE 0426 is the audit trail for EN 137 Type 2 compliance.

No HUD or PASS on the RN/MK2: building gauge discipline

The RN/MK2 standard configuration has no integrated HUD or PASS. Standalone PASS devices are required. Air monitoring is through the mechanical gauge — typically mounted on the low-pressure hose or cylinder neck. For departments that have switched from telemetry-equipped units to the RN/MK2 (or are using it for training), regular gauge check intervals must be defined and enforced in SOP. The absence of HUD increases the cognitive requirement for air management — this is a training consideration, not a safety deficiency if procedurally managed.

FAQ

Spasciani SCBA Air Time Calculator – RN/MK2 and SK Escape Set

Spasciani is an Italian manufacturer producing EN 137 certified SCBA for structural firefighting and industrial use, plus escape breathing devices (EEBD) for industrial and maritime emergency evacuation. The RN/MK2 is a full EN 137 Type 2 positive-pressure SCBA; the SK Escape Set is strictly an EEBD rated to EN 1146 for escape only, not entry into IDLH atmospheres. Understanding this distinction is critical before selecting a model — the operational scope and safety certification are fundamentally different between these two product types.

Spasciani RN/MK2: two connector types explained

The Spasciani RN/MK2 is available in two connector configurations: Type A, which uses the EN 148-3 standard screw-thread facepiece connection compatible with most European SCBA manufacturers, and Type BN, which uses Spasciani's proprietary snap connector. If your department operates mixed fleets, the connector type determines which facepieces are interchangeable between units. Air time is unaffected by connector type — the distinction is purely mechanical compatibility between facepiece and demand valve.

Spasciani SK Escape Set: EEBD, not structural SCBA

The SK Escape Set (SK 1203) is an Emergency Escape Breathing Device certified to EN 1146, not an EN 137 Type 2 SCBA. This is a critical distinction: EN 1146 EEBDs are certified for emergency escape only — moving from a hazardous atmosphere to safety. They are not certified for entry into IDLH atmospheres, search and rescue, or firefighting. Cylinders are small (2.0L to 3.0L) and duration is intentionally limited. The SK Escape Set should never be used as a substitute for a proper SCBA on operational entries.

EN 1146 vs EN 137: what the certifications mean

EN 137 Type 2 (used by RN/MK2) is the European standard for positive-pressure SCBA certified for firefighting in IDLH (immediately dangerous to life and health) atmospheres. EN 1146 (used by SK Escape) is the European standard for EEBDs — devices worn by building occupants, vessel crew, or industrial workers to escape from a hazardous atmosphere. They have different cylinder sizes, duration requirements, and facepiece designs. In planning air time for operational use, only EN 137 Type 2 units apply.

Spasciani RN/MK2 composite cylinder options

The RN/MK2 is available with 6.0L steel, 6.8L composite, and 9.0L composite cylinders, all at 300 bar service pressure. The composite (carbon/glass fibre) cylinders are lighter than steel for the same water volume. When calculating air time, the critical input is water volume and service pressure — composite vs steel does not change the air time formula, only the weight the firefighter carries.

Classic Italian design: what it means operationally

Spasciani has a long history as a European EN 137 manufacturer with a presence in Italian fire services, industrial facilities, and export markets. The RN/MK2 design prioritises simplicity and reliability. The absence of integrated HUD and PASS on the standard configuration means air management depends on mechanical gauge reading and training habits. Departments using Spasciani units without telemetry should emphasise physical gauge checks at regular intervals as part of standard SOP.
