One of the most common doubts buyers have when they hear “5 Bay – 20 Cabinets” is:
👉 “How are these 20 cabinets calculated?”
👉 “What exactly does 5 bays mean?”
👉 “How much floor space will it require in my office?”

This section provides a clear breakdown so buyers can visualize the system before purchase.

🔹 Step 1: What is a Cabinet (Body)?

A cabinet (or body) is one complete storage unit within the compactor.

Size per cabinet = 2505 mm (H) × 915 mm (W) × 450 mm (D)

Each cabinet = 5 adjustable/removable shelves

Compartments per cabinet = 6

👉 In this model, there are 20 cabinets in total.

🔹 Step 2: Understanding SFF, DFM & SFM

A compactor is built using three components:

SFF (Single Fixed Frame)

Static, does not move.

Open on one side only.

In this model → 5 cabinets (1 row of 5).

DFM (Double-Faced Movable)

Movable, open on both sides.

Each DFM = 2 rows of cabinets back-to-back.

In this model → 10 cabinets (5 on each side).

SFM (Single-Faced Movable)

Movable, open on one side only.

In this model → 5 cabinets (1 row of 5).

👉 Formula: Total Cabinets = SFF (5) + DFM (10) + SFM (5) = 20 Cabinets

🔹 Step 3: What is a Bay?

A bay is one continuous row of cabinets joined side by side.

Each cabinet width = 915 mm

A bay of 5 cabinets = 915 × 5 = 4575 mm (4.575 m) long

👉 In this configuration:

5 Bays = 5 continuous rows of 5 cabinets each

Together, they form the complete 20-cabinet system

🔹 Step 4: Floor Area Calculation

Let’s calculate the total footprint:

Width (row length)

5 cabinets per bay × 915 mm = 4575 mm (4.575 m)

Depth (system thickness)

SFF depth = 450 mm

DFM depth = 900 mm (double-faced)

SFM depth = 450 mm
👉 Total depth = 450 + 900 + 450 = 1800 mm (1.8 m)

Height

Non-standard = 2505 mm (2.505 m)

Aisle Requirement

Only 1 working aisle of 750–900 mm is needed for access.

Final Footprint

Width (length of row): 4575 mm

Depth: 1800 mm + aisle (750–900 mm) = 2550–2700 mm

Height: 2505 mm

👉 Total system area = 4575 × 2715 mm ≈ 12.4 m²

This means the compactor can replace 20 almirahs while occupying the footprint of just 5–6 almirahs.

🔹 Step 5: Visualization for Buyers

Imagine standing in front of the unit:

The first row (SFF) is fixed and does not move.

The middle row (DFM) is movable and open on both sides → this row equals 10 cabinets.

The last row (SFM) is movable and open on one side.

When all bays are closed, the system looks like a solid wall of steel cabinets. When you slide one movable row, it opens an aisle for file access.

🔹 Step 6: Why This Explanation Matters

For buyers, this breakdown explains:

How the 20 cabinets are derived → 5 (SFF) + 10 (DFM) + 5 (SFM).

What “5 Bay” means → 5 continuous rows of cabinets, each 4575 mm wide.

Exact floor area needed → ~12.4 m² including the aisle.

How it saves space → only 1 working aisle instead of 20 for almirahs.
