You should expect the same accuracy and consistency from the regulators you choose, as you do from the gases you buy. Here at Premier Industries, we designed two demand flow regulators to meet rigid industry specifications while keeping in mind the specific needs and expectations of our customers. Our demand flow regulators are offered in a variety of materials and configurations to integrate seamlessly into your application.
- Commonly used with: portable gas detectors, gas analyzers, calibration gases, and pump-drawn instruments
- Highly sensitive, patented, single-stage design
- Available with an optional transducer for increased precision and automation
- Optional stainless steel bodies and wetted components provide minimum degradation to cylinder gases
Premier 4902 Series Demand Flow Regulators
Premier’s patented, efficient, and easy to use 4902 Series demand flow regulators (also referred to as “sample regulators” and “vacuum actuated regulators”) supply gas as demanded by an analyzer and automatically shut off. The highly sensitive, patented, single stage design allows for reduced testing time, permitting the flow of gas at less than one inch water column. Furthermore, the high flow capacity of the Premier 4902 Series demand flow regulator enables multiple analyzers to be tested on a single docking station.
Premier 4903 Series, Miniature Demand Flow Regulators
These patented, compact, and economical vacuum actuated regulators eliminate the need for shut off valves, sample bags, or specially trained operators, making your calibrations quick & easy. Premier 4903 Series miniature demand flow regulators supply precise amounts of gas as demanded by an analyzer/pump drawn instrument; as long as the pump is active, the regulator will remain “open” and gas will flow, when the pump stops, the regulator will turn off. The result? Less wasted gas, and lower calibration costs.
