Category: A3-A2L SPECIALIST
Notes: INNOVATION OF THE YEAR NOMINEE - ATMOSummit America 2025
OLAB FastPro (Patent Pending) is the new benchmark for safety management in professional A3-A2L systems, up to 90 bar (1305 psi). Recognised as an Innovation of the Year nominee at the ATMO Summit America 2025, and built around OLAB’s FastSystem (Patented) connection technology, this 360° swivelling change-over represents the perfect combination of innovation, efficiency and reliability.
FastPro installs in 30 seconds, with no need for Teflon, Loctite, or specialised personnel. The FastSystem (Patented) connection enables a simple, fast, and precise assembly, significantly reducing time, cost, and operational complexity. Even in challenging environments or tight spaces, FastPro adapts without the need for rework. Thanks to the fully swivelling design of the entire valve body and safety valves, it allows complete orientation before and after installation, making the system easy to access, configure, and adapt to any plant layout.
Each potential leak point is sealed with double OLAB-certified, 100 % PFAS-FREE HNBR O-Rings, ensuring perfect and stable sealing even under extreme conditions. The entire component is 100% PFAS-FREE, guaranteeing maximum environmental safety and full compliance with new regulations. FastPro is available with a customisable sleeve in brass or stainless steel, in both threaded and weldable versions, to suit every project requirement and installation standard. It is designed to ensure constant system protection: one valve remains active while the other is isolated, allowing safe replacement without stopping the system.
ProShield safety valves connect exclusively to FastPro through the FastSystem (Patented) interface, ensuring precise, leak-free installation. Equipped with ISO cylindrical gas thread and OLAB-certified, 100% PFAS-FREE HNBR O-Rings, these valves also allow controlled venting of excess refrigerant gas during replacement—a key feature in high-pressure transcritical systems. ProShield valves are certified for both subcritical (up to 60 bar) and transcritical (up to 300 bar) systems, in accordance with the most demanding international regulations: D.E. 2014/68/EU (PED), ASME XIII, SELO, UKCA, EAC TR CU 032-010-012, ATEX, UKEX, and Canadian registration. The highest standard of safety, innovation, and sustainability.
FastPro and ProShield together offer a revolutionary, integrated solution: installation in 30 seconds even on A3-A2L systems at 90 bar (1305 psi); perfect sealing with OLAB-certified, 100% PFAS-FREE HNBR O-Rings; 360° rotation before and after installation; customisable sleeve in brass or stainless steel; compatibility with critical systems and international certifications. A complete, pressure-proof solution designed to simplify installation, ensure continuous safety, eliminate leakage, and reduce environmental impact—without compromise.
Technical features:
COMPATIBLE A3–A2L REFRIGERANT GASES
HFC, HFO, and HFO/HFC blends: R404A, R407C, R410A, R507, R32, R134a (up to +125°C / 257°F).
HFO and HFO/HFC blends: R1234ze, R448A, R449A, R450A, R452A, R1234yf.
HC: R290, R600, R600a.
Products equipped with HNBR seals must not be installed on systems using HCFCs (R22) or any refrigerants mixed with mineral oils or alkylbenzene lubricants.
Our HNBR compound seals have been specifically designed and manufactured for compatibility with A3 and A2L refrigerant gases (as defined in ASHRAE Standard 34). However, due to the countless variables involved in real-world applications—such as pressure, temperature, and mixing ratios—an application-specific validation on the system is always required.
100% PFAS-FREE
Fully certified 100% PFAS-FREE component.
100% NO LEAKAGE
Total sealing up to 90 bar (1305 psi) ensured by double O-Rings in OLAB-certified HNBR 100% PFAS-FREE at every potential leakage point.
FASTSYSTEM CONNECTION: 30-SECOND INSTALLATION
No Teflon, no Loctite, no specialized personnel required.
360° ORIENTATION
Body and safety valves freely rotate before and after installation, even in tight spaces.
CHOOSE YOUR CONNECTION
Customizable sleeve for any layout: brass or stainless steel, threaded or socket weld.
EXCLUSIVE OLAB PROSHIELD SAFETY VALVE
Dedicated connection to OLAB ProShield safety valves, certified up to 300 bar.
UNINTERRUPTED OPERATION
One valve remains active while the other is isolated: replacement without system shutdown.
CONTROLLED VENTING
Cylindrical thread: safe refrigerant gas discharge during PRV replacement.
TOTAL SAVINGS
Less time, less labor, lower operational costs.
