Regin S104 Leak Detection Emitters — 5-Pack, Dense Visible Cloud, 3‑Minute Dispersion, 1,200 cu ft Coverage

Regin S104 Emitters are single-use pellets that release a dense, visible cloud in approximately three minutes, each dispersing up to 1,200 cubic feet for leak detection and qualitative airflow testing.

Designed for building engineers, HVAC technicians and maintenance teams, the S104 is a compact, easy-to-use aerosol source that makes airflow patterns and leaks visible without specialized machinery. Each pack includes five emitters; every pellet reliably produces a concentrated, viewable plume that helps you trace drafts, locate gaps, and demonstrate airflow direction in rooms, ductwork, or around windows and doors.

How long does each emitter last and how much volume does it cover?

Each S104 pellet releases its cloud over a roughly 180-second period and is formulated to influence up to 1,200 cubic feet of space per unit. That duration and coverage are ideal for short inspections and demonstrations where immediate visual evidence of movement is needed.

• Active release time: approximately 180 seconds.
• Coverage per emitter: up to 1,200 cubic feet.
• Five individual pellets per retail pack for multiple tests.

What types of tests or inspections are the emitters best for?

S104 pellets are intended for qualitative leak detection and airflow visualization rather than precise quantitative measurement. Use them to reveal drafts, confirm ventilation paths, show pollutant transport routes, or validate the effects of seals and barriers in buildings and duct systems.

• Detect visible leakage around doors, windows, and fittings.
• Visualize airflow direction and circulation in rooms and ducts.
• Confirm effectiveness of newly installed seals or barriers.

How should the product be stored and handled for best results?

Store unused S104 emitters in a cool, dry place out of direct sunlight to preserve performance. Following the manufacturer’s storage guidance helps maintain potency for up to two years; handle each pellet per included instructions and use outdoors or in well-ventilated areas appropriate to the material’s intended testing use.

• Recommended shelf life: up to two years when stored cool and dry.
• Keep in original packaging until needed to protect pellets.
• Follow on-package safety and disposal instructions after use.

How many tests can I perform with one pack and what’s included?

A single pack contains five S104 emitters, so you can perform up to five separate tests or demonstrations. The compact size and single-use format make them convenient for fieldwork, training, or spot checks without extra equipment.

• Pack quantity: five emitters per box.
• One emitter per test; no refilling required.
• Portable format for on-site troubleshooting and demonstrations.

Who is this for: The Regin S104 Emitters are made for professionals and facilities staff who need a fast, visible way to identify leaks or show airflow paths without complex instrumentation. Ideal for HVAC technicians, building inspectors, energy auditors, and training instructors who require reliable, single-use visual tracer sources for short-duration inspections and demonstrations.
