DEMA 801GAP Bottle Fill Dispenser – Air Gap Backflow Preventer, 3.8 L/min

Description

Precise chemical dilution with compliance built in — the 801GAP turns any wall into a professional chemical dispensing station.

The DEMA 801GAP Bottle Fill Dispenser is a wall-mounted chemical dilution station engineered for commercial environments where accuracy, compliance, and chemical waste reduction are non-negotiable. Delivering a fixed 1 GPM (3.8 L/min) flow rate, it ensures every spray bottle or small container is filled to a consistent, repeatable dilution ratio — eliminating guesswork, reducing chemical overuse, and keeping cleaning programs on specification. The integrated air gap (GAP) backflow preventer physically separates the water supply from the chemical stream, providing the highest level of cross-contamination protection and full compliance with Australian plumbing codes.

Installation is straightforward — the 801GAP mounts directly to the wall in any cleaning station, utility room, or chemical storage area. Quick-change metering tips allow facilities teams to adjust dilution ratios without tools or specialist knowledge, while clearly labelled ports minimise setup errors and speed up changeovers. Built from chemical-resistant materials throughout, the 801GAP is engineered to handle the daily demands of high-traffic commercial facilities without deterioration or downtime.

Why professionals choose the DEMA 801GAP

• Air Gap (GAP) Backflow Prevention — The integrated air gap physically breaks the connection between the water supply and the chemical stream — the most reliable backflow protection method, and fully compliant with Australian plumbing codes for commercial installations.
• Fixed 1 GPM Flow for Consistent Dilution — Every fill delivers a repeatable 1 GPM (3.8 L/min) flow rate, ensuring spray bottles are filled to the correct concentration every time — no over-dilution, no chemical waste, no variation between operators.
• Quick-Change Metering Tips — Swap dilution ratios in seconds without tools — quick-change metering tips make it easy to adjust the unit for different chemicals or cleaning programs across the same facility.
• Compact Wall-Mount Design — Installs neatly on any wall surface, keeping floor space clear and putting chemical dispensing exactly where cleaning teams need it — in the utility room, cleaning station, or corridor cupboard.
• Chemical-Resistant Construction — Durable chemical-resistant materials protect the unit against daily contact with concentrated cleaning chemicals, disinfectants, and sanitisers in demanding, high-traffic commercial environments.

Specifications

Where the DEMA 801GAP works best

• Healthcare & Aged Care Facilities — Where plumbing compliance is mandated and chemical dilution accuracy directly affects infection control outcomes — the 801GAP ensures every bottle is filled to the correct concentration, every time.
• Commercial Cleaning & Janitorial Operations — Centralised dispensing stations eliminate manual measuring of concentrated chemicals — reducing spills, waste, over-concentration errors, and the risk of incorrect dilutions reaching surfaces.
• Education & Institutional Cleaning — Schools, universities, and large institutions benefit from fixed-ratio dispensing that keeps cleaning programs consistent across multiple buildings, floors, and cleaning staff shifts.
• Food Service & Hospitality — Kitchens and cafeterias require precise dilution of food-safe sanitisers — the 801GAP delivers the right concentration at every fill to keep surfaces compliant with food safety standards.
• Retail & Commercial Property Maintenance — Compact wall-mount installation suits utility rooms, back-of-house areas, and cleaning cupboards across retail and commercial properties where space and compliance both matter.

Frequently asked questions

What is an air gap backflow preventer and why does it matter?

An air gap (GAP) backflow preventer physically separates the water supply outlet from the chemical dispenser — creating a gap that prevents chemical from ever siphoning back into the potable water supply. It is the most reliable backflow protection method and is required by Australian plumbing codes in most commercial installations where chemical dispensers connect to a water supply.

Can the dilution ratio be changed on the DEMA 801GAP?

Yes. The 801GAP uses quick-change metering tips that can be swapped to alter the dilution ratio without any tools. This makes it straightforward for facilities managing multiple chemical programs to adjust the unit in seconds for different cleaning products or areas.

Does the 801GAP require a licensed plumber to install?

Connection to a water supply line should be performed by a licensed plumber in accordance with Australian plumbing regulations. The unit itself is wall-mounted and designed for straightforward installation — it ships with an installation guide and metering tips included.

What types of chemicals can be used with the DEMA 801GAP?

The 801GAP is built with chemical-resistant components suitable for most commercial cleaning chemicals, disinfectants, and sanitisers. Always verify your specific chemical’s compatibility with DEMA specifications and the chemical manufacturer’s guidelines before use.
