DEMA Trapper Drain & Odour Dispenser – Automated Dosing

Description

Set it, forget it, and eliminate drain odour at the source — the DEMA Trapper automates drain maintenance and odour control in one intelligent dispenser.

The DEMA Trapper Drain & Odour Control Dispenser (2507B.E) is an automated peristaltic dosing system that eliminates the guesswork — and the manual labour — from commercial drain maintenance and facility odour control. Programmable via a clear LCD display and intuitive 4-button interface, the Trapper automatically doses drain maintenance product or bio-enzymes into drains at pre-set intervals to prevent grease build-up, eliminate biofilm, reduce blockages, and neutralise drain odours at the source — keeping commercial kitchens, washrooms, hospitality facilities, and institutional venues smelling clean and drains running freely without ongoing staff intervention.

The Trapper’s dual-mode design makes it immediately adaptable for odour suppression as well — a simple programming change and part swap converts it to Trapper OC mode, which uses a configurable brass spray nozzle (adjustable from stream to mist) to apply deodorising product directly into the surrounding air. Water-resistant construction supports under-counter and low-wall installation close to drain points, while a toolless quick-change pump and fast snap-mounting bracket enable rapid maintenance without specialist tools or full unit removal. A 24/7 battery monitor with low battery warning and plug-n-go electrical connection ensure maximum uptime and the simplest possible installation experience.

Why professionals choose the DEMA Trapper

• Dual-Mode: Drain Dosing & Odour Suppression — Switch between automated drain maintenance dosing and air odour suppression with a programming change and simple part swap — one unit that adapts to both drain health and ambient odour control as your facility’s requirements change.
• Automated Programmable Dosing — Clear digital programming with intuitive controls automates drain treatment at pre-set intervals — eliminating manual dosing, reducing product waste, and ensuring consistent drain maintenance without staff intervention or oversight.
• Toolless Quick-Change Pump & Snap Bracket — The peristaltic pump changes without tools in seconds, and the fast snap-mounting bracket allows rapid removal and reattachment during maintenance — minimising downtime and eliminating the need for specialist service tools on-site.
• Water-Resistant for Under-Counter Installation — Water-resistant components allow installation under counters, at low-wall positions, and in moisture-prone areas close to drain points — keeping the Trapper where it needs to be for effective, proximate dosing.
• 24/7 Battery Monitor & Plug-N-Go Connection — Continuous battery monitoring with low battery warning ensures uninterrupted automated operation, while the plug-n-go electrical hookup makes installation, disconnection, and reconnection fast and simple without electrical specialist involvement.

Specifications

Where the DEMA Trapper works best

• Commercial Kitchen Drain Maintenance — Automatically dose bio-enzymes or drain treatment product into kitchen drains at pre-set intervals — breaking down grease, preventing fat accumulation, eliminating food waste odour, and keeping drainage systems clear without daily manual treatment.
• Washroom & Restroom Odour Control — Install near floor drains and urinal traps to neutralise drain odours at the source — programmed dosing eliminates the biofilm and bacteria responsible for persistent washroom malodour between cleaning cycles.
• Hospitality & Hotel Facilities — Automated drain maintenance and odour control across kitchen, bar, laundry, and bathroom areas — reducing reactive drain callouts, lowering maintenance costs, and keeping guest-facing areas continuously fresh.
• Healthcare & Aged Care Facilities — Consistent automated drain dosing in utility rooms, sluice areas, and washrooms — preventing drain odour issues that create compliance risk or complaint-generating conditions in sensitive care environments.
• Retail & Commercial Property Management — Set-and-forget drain treatment for shopping centres, office buildings, and commercial properties where regular manual drain maintenance is impractical — the Trapper keeps drains treated automatically on schedule without staff involvement.

Frequently asked questions

What is the difference between drain maintenance mode and odour suppression mode?

In drain maintenance mode, the Trapper automatically doses product (typically a bio-enzyme or drain treatment chemical) directly into the drain at pre-set intervals to prevent grease build-up, eliminate biofilm, and reduce blockages. In odour suppression mode (Trapper OC), a brass nozzle replaces the drain dosing tube and sprays deodorising product into the surrounding air — addressing ambient facility odour rather than drain health. Switching between modes requires a programming change and a simple part swap.

Does the Trapper require specialist installation?

No. The Trapper uses a plug-n-go electrical connection for quick hookup, a snap-mounting bracket for fast wall installation, and a toolless pump requiring no tools to change or service. Water-resistant construction allows under-counter or low-wall installation near drain points without specialist plumbing or electrical work.

Is there a portable version for locations without wall access?

Yes. The Trapper Pail is a battery-operated version with a bracket that attaches directly to a five-gallon pail lid — requiring no wall mounting, no electrical connection, and no fixed installation. It can be positioned under counters or moved between locations as needed, making it ideal for areas where wall mounting is impractical.

What chemicals can be used with the DEMA Trapper?

The Trapper is compatible with commercial drain maintenance chemicals, bio-enzyme products, and liquid deodorising agents. Contact Prochemicals for chemical recommendations matched to your specific drain type, application, and odour control requirements.
