Planning Your Aerosol Production Floor
A well-planned factory layout improves safety, reduces material handling time, and increases throughput. This guide covers space requirements for each production tier and the key zones every aerosol facility needs.
Space Requirements by Production Tier
| Tier | Min. Floor Space | Recommended | Ceiling Height |
|---|---|---|---|
| Semi-Auto Stations | 30 m² | 50-80 m² | 3.0 m |
| 4-in-1 Compact System | 10 m² (machine only) | 40-60 m² (with workflow) | 3.0 m |
| Entry Full-Auto Line | 80 m² | 120-200 m² | 3.5 m |
| High-Speed Full-Auto | 150 m² | 300-500 m² | 4.0 m |
Multiplied by 2.5-3x for total facility (production + storage + office). A 120 m² production area typically means a 350-400 m² total facility.
Essential Facility Zones
Zone 1: Raw Material Storage (20-30% of total floor space)
- Can Storage: Empty aerosol cans are bulky. Plan pallet racking and FIFO (first-in-first-out) flow.
- Concentrate Storage: Temperature-controlled area (15-25°C typical) for chemical concentrates.
- Propellant Storage: Critical safety zone. Separate, ventilated, explosion-proof area for LPG/DME cylinders or bulk tanks. Minimum 5 m distance from production area per most fire codes.
- Packaging Materials: Valves, actuators, caps, cartons — dry storage with pest control.
Zone 2: Production Line (25-35% of total floor space)
The production flow should be linear (U-shape or straight line) to minimize material handling:
- Can feeding → unscrambler or manual loading station
- Liquid filling → semi-auto or automatic station
- Valve placement + crimping/sealing → crimping station
- Propellant gassing → gas filling station (near propellant storage for short pipe runs)
- Hot water bath → FD9955 leak tester (3-5 min dwell time determines conveyor length)
- Checkweigh + coding → checkweigher + inkjet coder
- Actuator + cap placement → actuator placer + cap placer
- Packaging → carton sealing, palletizing
Zone 3: Quality Control Lab (5-10% of floor space)
Minimum equipment: precision balance, pressure gauges, water bath for leak testing samples, can seam micrometer, burst pressure tester. Budget 15-25 m² for a basic QC lab.
Zone 4: Finished Goods Warehouse (20-30% of floor space)
Pallet racking for filled, labeled, and cartoned products. Temperature control if products are temperature-sensitive. Allow space for order picking and loading dock access.
Zone 5: Utilities & Services (5-10%)
Compressed air system, electrical panels (explosion-proof where required), ventilation fans, fire suppression system, staff amenities (locker room, washroom).
Critical Safety Distances
| Requirement | Minimum Distance |
|---|---|
| Propellant storage to production | 5-15 m (varies by local code and propellant volume) |
| Gas filling station to ignition sources | 3 m minimum; explosion-proof electrical within 5 m radius |
| Aisle width for material handling | 1.5-2.5 m (pallet jack vs. forklift) |
| Emergency exits from production area | 2 exits minimum, opposite walls, travel distance ≤ 25 m |
Frequently Asked Questions
Can I run a semi-auto line in a standard warehouse?
Yes — most semi-automatic equipment runs on standard single-phase or three-phase power and doesn’t require specialized facility modifications beyond basic ventilation. Many startups begin in converted warehouse spaces of 50-100 m².
Do I need a separate building for propellant storage?
For LPG and DME: yes, most fire codes require an external storage cage or separate structure with explosion-proof electrical and ventilation. For compressed gases (N₂, CO₂): cylinder storage within the main facility is typically acceptable with proper securing and ventilation.
What’s the most common layout mistake?
Underestimating material flow space. A production line that fits on paper becomes congested when you add pallets of empty cans, drums of concentrate, and finished product waiting for QC release. Add 40-50% to your initial space estimate for workflow and staging areas.
