Mastercool 90066-220-BLSF-ATEX — ATEX Spark-Free Vacuum Pump for Flammable Refrigerants

ATEX-Certified Spark-Free Vacuum Pump for Explosive Environments

Certificate Number: II 3G Ex ec nC h IIA T4 Gc

The Mastercool 90066-220-BLSF-ATEX is a certified explosion-proof vacuum pump engineered specifically for working with flammable refrigerants and in potentially explosive atmospheres. This is the vacuum pump you need for compliance with ATEX Directive requirements when servicing systems with A2L and A3 flammable refrigerants including R32, R454B, R1234yf, and R290.

ATEX Certification — Engineered for Safety

Our certified equipment eliminates all potential ignition sources to ensure safe operation in hazardous environments:

• Spark-Free Design — Eliminates electric sparks, arcs, and electrostatic discharges
• No Ignition Sources — Engineered to prevent electromagnetic waves, ionising radiation, hot surfaces, flames, mechanically generated sparks, and compression ignition
• Full ATEX Compliance — Certified for explosion-proof operation across various protection categories
• A2L/A3 Refrigerant Approved — Safe for use with all air conditioning refrigerants including flammable A2L (mildly flammable) and A3 (highly flammable) classifications

Critical for Modern Refrigerants

As the HVAC industry transitions to lower-GWP refrigerants, many new alternatives are classified as mildly flammable (A2L) or flammable (A3). This ATEX-certified pump ensures you can service these systems safely and legally:

• R32 (A2L) — Common in residential air conditioning
• R454B (A2L) — Replacement for R410A
• R1234yf (A2L) — Automotive air conditioning
• R290 (A3) — Propane-based natural refrigerant
• Plus all traditional refrigerants (R134a, R404A, R407C, R22, R410A)

Black Series Performance You Trust

Built on Mastercool's proven Black Series platform, this pump delivers professional-grade performance with added safety certification:

• Powerful Evacuation — 170 lit/min at 60Hz (142 lit/min at 50Hz) pulls deep vacuum to 15 microns
• 2-Stage Design — Superior vacuum depth for thorough moisture removal
• Enhanced Durability — Refined cartridge machining and upgraded seals extend pump life
• Reduced Friction — Expanded internal oil path minimises heat buildup during extended operation
• Moisture Protection — Gas ballast valve prevents oil contamination in high-moisture conditions

Professional Features

• Manifold Valve — Isolates pump from system during leak testing; 3 inlet ports (1/4", 3/8" SAE, 1/2" ACME)
• Advanced Cooling — High-volume fan and cooling fins maintain optimal operating temperature
• Oil Management — Check valve prevents backflow; large sight glass with max/min indicators; easy-access drain valve
• Thermal Protection — Motor protection with on/off rocker switch
• Portable Design — Easy-grip handle and reinforced base for stable field positioning
• Easy Maintenance — Removable vapour discharge/oil fill port (440ml capacity)
