DEMA 802GAP Bucket Fill Dispenser – 15 L/min, Air Gap Backflow Preventer

Description

Fill a mop bucket in seconds, not minutes — the 802GAP is built for high-throughput cleaning operations that cannot afford to wait.

The DEMA 802GAP Bucket Fill Dispenser is a high-flow chemical dilution station purpose-built for large-volume filling tasks in commercial and industrial environments. With a 4 GPM (15.1 L/min) flow rate — four times the output of the 801GAP bottle fill model — the 802GAP is designed to fill mop buckets, auto scrubbers, floor cleaning machines, and large containers quickly, accurately, and at consistent dilution ratios every time. The result: faster cleaning turnovers, less time lost at the fill station, and cleaning programs that stay on specification regardless of who is operating the dispenser.

Like all DEMA GAP dispensers, the 802GAP features a fully integrated air gap backflow preventer for complete protection of the potable water supply and compliance with Australian plumbing codes. One-handed activation keeps filling fast and efficient, while easy-to-change metering tips allow dilution ratios to be adjusted without tools — ideal for facilities managing multiple chemical programs or transitioning between products. Wall-mounted, clearly labelled, and built from chemical-resistant materials, it installs in any utility room, plant room, or equipment bay and delivers reliable performance shift after shift.

Why professionals choose the DEMA 802GAP

• 4 GPM High-Flow Output — At 15.1 L/min, the 802GAP fills a standard 10-litre mop bucket in under a minute — dramatically faster than a 1 GPM bottle fill dispenser and built to keep high-throughput cleaning teams moving without delays at the fill station.
• Built for Buckets & Auto Scrubbers — Engineered specifically for large-volume containers — mop buckets, auto scrubber tanks, floor cleaning machines, and industrial vessels — where fast, accurate fill is central to operational efficiency.
• Air Gap (GAP) Backflow Prevention — Integrated air gap protection physically separates the water supply from the chemical stream — the highest-rated backflow prevention method and fully GAP-compliant with Australian plumbing standards.
• One-Handed Activation — Activate the fill with one hand while managing the bucket or scrubber with the other — fast, controlled operation designed for busy cleaning environments where every second counts.
• Easy-Change Metering Tips — Swap dilution ratios without tools in seconds — quick-change metering tips make the 802GAP fully adaptable to different chemical products and cleaning programs across the same facility.

Specifications

Where the DEMA 802GAP works best

• Commercial Cleaning & Facility Maintenance — High-throughput facilities running multiple cleaning teams need fast bucket fills — the 802GAP’s 4 GPM output eliminates bottlenecks at the chemical station and keeps operations on schedule.
• Healthcare & Aged Care Operations — Where cleaning frequency is high and dilution accuracy directly affects infection control — the 802GAP ensures every bucket is filled to the correct concentration, consistently and quickly.
• Schools, Universities & Institutional Facilities — Large campuses with multiple cleaning teams and broad floor areas benefit from high-flow dispensing that reduces fill time and maintains consistent dilution across all staff and buildings.
• Contract Cleaners & Large-Scale Operations — Contractors responsible for large sites, multi-level buildings, or shift-based operations need a dispenser that keeps pace with volume demands — the 802GAP is built for exactly that.
• Industrial Sites & Warehouses — Larger containers, longer distances, and higher cleaning demands make high-flow dispensing essential — the 802GAP handles big-volume fills that would be impractical at 1 GPM.

Frequently asked questions

What is the difference between the DEMA 801GAP and the 802GAP?

The key difference is flow rate and application. The 801GAP delivers 1 GPM (3.8 L/min) and is designed for filling spray bottles and small containers with precision. The 802GAP delivers 4 GPM (15.1 L/min) and is purpose-built for large-volume fills — mop buckets, auto scrubbers, and large containers where speed and throughput are the priority.

How long does it take to fill a mop bucket with the 802GAP?

At 4 GPM (15.1 L/min), a standard 10-litre mop bucket fills in under a minute. A 15-litre bucket takes approximately 60 seconds at full flow — significantly faster than lower-flow dispensers, reducing downtime between cleaning tasks.

Can the dilution ratio be changed on the 802GAP?

Yes. The 802GAP uses easy-change metering tips that can be swapped without tools to adjust the dilution ratio for different chemicals or cleaning programs — making it adaptable to multi-product facilities without any specialist knowledge.

Does the 802GAP comply with Australian plumbing regulations?

Yes. The integrated air gap (GAP) backflow preventer meets Australian plumbing code requirements for chemical dispensers connected to a water supply. As with all plumbing connections, the water supply line should be connected by a licensed plumber.
