CHAD High-Pressure Brass Oxygen Flowmeter Regulators
0ā8 LPM or 0ā15 LPM Click-Stop Dial
ASTM-G175-03 Ignition Tested
Integrated 20-Micron Sintered Bronze Filter
FDA Class I Medical Device
Executive Product Overview
The CHAD Oxygen Flowmeter Regulator series (Models CH4808-L-BLUE and CH4815-L-BLUE) is a precision-engineered pressure-reducing valve line designed for safe, metered delivery of medical oxygen. Built with a heavy-duty internal brass body and an anodized blue aluminum flow control dial, these click-style regulators combine fire-safe internal metallurgy with lightweight external housing for institutional and homecare environments.
Featuring a standard CGA-870 pin-index yoke connection and high-performance Viton/brass sealing washers, each unit mounts securely onto post-valve medical oxygen cylinders (such as D and E tanks). The integrated 20-micron sintered bronze inlet filter traps microscopic particulates, protecting internal valve mechanics from high-pressure scale. Tested 100% in the USA and certified to ASTM-G175-03 promoted ignition standards, CHAD regulators maintain a stable 50 PSI regulated outlet pressure across inlet tank pressures from 500 to 3,000 PSI.

Key Performance & Operational Features
- Tactile Click-Stop Flow Dial: Precision detented rotary selector prevents flow setting drift or unmonitored creeping.
- Heavy-Duty Fire-Safe Brass Core: Solid brass high-pressure internal gas path resists promoted ignition under compression spikes.
- ASTM-G175-03 Ignition Certified: Passes rigorous promoted ignition safety standards for high-pressure medical oxygen systems.
- Integrated 20-Micron Sintered Bronze Filter: Traps particulate matter and pipe scale before gas enters the micro-metering orifices.
- High-Performance Viton & Brass Washers: Provides a durable, leak-free seal against the cylinder post across repeated tank swaps.
- 100% USA Quality Control Tested: Every unit is individual pressure- and flow-calibrated prior to factory release.

Facility Procurement & Risk Mitigation Insight
Standardizing cylinder fleets on CHAD High-Pressure Brass Regulators enhances patient safety by combining ASTM-G175-03 ignition-tested brass internals with a 20-micron sintered bronze filter. The tactile click-stop dial eliminates flow rate creeping, protecting patients from under- or over-oxygenation during transport.
Product & Compliance FAQs
Q: What regulatory oversight governs CHAD Oxygen Flowmeter Regulators?
A: Pressure regulators sold as standalone hardware accessories are classified by the FDA as Class I medical devices (HCPCS E1353). They do not require a medical prescription or professional license to purchase.
Q: What is the benefit of the 20-micron sintered bronze inlet filter?
A: The 20-micron filter sits inside the CGA-870 inlet port to capture rust, metal shavings, and environmental dust from high-pressure cylinders, preventing particulate contamination and protecting the internal valve mechanism.
Q: What cylinder post types does the CGA-870 connection fit?
A: The CGA-870 yoke connection fits all standard medical post-valve cylinders, including portable ambulatory aluminum tanks such as M6, M9, C, D, and E oxygen cylinders.
