Gas Arc Regulators, part of the ESAB family of brands, are precision-engineered gas control products for industrial, laboratory, speciality, and medical applications. They are available in different series tailored to specific gas purity requirements and applications.
Product Series Overview
Gas Arc offers several main product platforms, each designed for specific gas purity levels and applications:
Tech Master (GP Series):
Designed for technical grade gases up to 4.5 (99.995%) purity, suitable for non-corrosive and non-toxic gases in industrial applications like engineering and fabrication.
Lab Master (LG Series):
For high purity gases up to 5.0 (99.999%) purity, manufactured from nickel-plated brass. Applications include food production, packaging, and education research.
Spec Master (HP Series):
For high purity gases up to 6.0 (99.9999%) purity, also made from nickel-plated brass barstock. Used in analytical facilities and research where very low impurity levels are required.
Chem Master (SG Series):
Specifically designed with stainless steel for use with corrosive and toxic gases up to 6.0 purity, ensuring accurate pressure control in demanding laboratory environments.
These regulators come in both single-stage and multi-stage configurations, with multi-stage designs providing more constant delivery pressure as cylinder pressure decreases.
Specialist and Laboratory Gas Distributors
FTI Ltd:
A UK distributor focusing on the special gases market, FTI supplies Gas Arc regulators to academia, government, and research sectors, as well as to industrial clients.
Q: Are Gas Arc Regulators Good Quality
A: Yes, Gas Arc Regulators are widely regarded as a high-quality, premium brand in the gas control industry. They are engineered for precision, durability, and safety across demanding industrial, laboratory, and medical applications.
Key reasons for their strong reputation include:
Superior Construction:
Gas Arc regulators are built with robust materials like brass barstock (Tech Master series) or 316L stainless steel (Chem Master series) for maximum durability and corrosion resistance in harsh environments.
Precision and Stability:
The multi-stage regulators, in particular, are renowned for providing very stable and consistent outlet pressure, which is critical for applications like analytical research, high-quality welding, and diving operations.
Advanced Features:
They incorporate superior components such as next-generation diaphragms that protect against hydrogen embrittlement and surface corrosion, encapsulated seat designs to minimise leaks and contamination risks, and robust piston technology for high-pressure control.
Industry Standards & Safety:
All equipment is designed, manufactured, and tested under strict quality management systems (e.g., BS EN ISO 9001 and EN ISO 2503 standards) and are involved with industry safety bodies like the British Compressed Gases Association (BCGA)
Specialised Applications:
The brand offers dedicated product lines (Lab Master, Spec Master, Chem Master) tailored for specific high-purity and corrosive/toxic gases, ensuring the integrity of the gas supply for critical processes. While some very basic/generic regulators exist on the market at a low price point, Gas Arc regulators are positioned at the premium end, with prices reflecting their engineering quality and the critical nature of their applications. They are considered a reliable and safe investment for professional use.
