01 Answer first
How should a compressor and receiver be sized for PET water-bottle blowing?
Use the actual bottle and machine air-consumption curve at required pressure, then add simultaneous users, treatment and distribution losses, leakage, receiver charge and recovery, operating cases, ambient or altitude derating and justified margin. Separate high-pressure blowing air from lower-pressure service and control duties.

Questions for Sizing the Blowing-Air System by Operating Case
Own pressure, quality, flow, transients and storage for PET blowing here; site-wide utility distribution stays with the utility owner page.
What air-demand cases should size the blowing compressor?
Use the confirmed bottle formats, cavity plan, cycle, machine recovery characteristics, leakage allowance and simultaneous operating states.
- Inputs needed
- Blower data; SKU schedule; cycle; cavities; low- and high-pressure demands; simultaneity; leakage basis.
- Decision evidence
- Mode-based demand schedule linked to supplier data and approved production cases.
How should the air receiver be sized?
Base storage on acceptable pressure swing, compressor control, peak duration and safe recovery for defined transitions rather than a generic volume rule.
- Inputs needed
- Peak profile; pressure limits; compressor response; receiver location; piping volume; safety requirements.
- Decision evidence
- Dynamic or conservative sizing calculation and reviewed control sequence.
Which compressed-air quality controls are required?
Define filtration, drying, oil-control, condensate management and monitoring for the equipment and product-risk boundary.
- Inputs needed
- Compressor type; air contact points; dew point; filtration; ambient humidity; local quality plan.
- Decision evidence
- Approved air-quality specification, treatment train, sampling and maintenance records.
How should hot or high-altitude conditions affect selection?
Obtain supplier derating for the actual inlet temperature, altitude, ventilation and cooling conditions and verify the plant-room design.
- Inputs needed
- Altitude; design ambient; humidity; room heat rejection; inlet and cooling conditions; power supply.
- Decision evidence
- Manufacturer-supported derating and site ventilation and cooling review.

Position in the project journey
PET package and blowing definition - before preform, mold, compressor, chiller and line release.
03 Buyer inputs
What the buyer should prepare
- Approved bottle demand and blower operating cases
- Existing low- and high-pressure air-system data
- Ambient, altitude, power and room conditions
- Redundancy, maintenance and production-continuity requirements
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Bottle-specific air consumption and pressure envelope
- Compressor, booster, dryer, filter and receiver calculation
- Control, alarm, isolation and terminal acceptance conditions
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Answer First: Release the High-Pressure Air Capacity Basis
Use the actual bottle and machine air-consumption curve at required pressure, then add simultaneous users, treatment and distribution losses, leakage, receiver charge and recovery, operating cases, ambient or altitude derating and justified margin. Separate high-pressure blowing air from lower-pressure service and control duties.
Define the Decision Boundary
Define reference formats, cycles, blower count, startup and recovery events, compressor control range, booster inlet conditions, air quality, drying, filtration and standby philosophy. Model pressure at the machine, not only at the compressor discharge.
Buyer Inputs for Release the High-Pressure Air Capacity Basis
For PET Bottle Blowing Compressor Sizing and Air-Receiver Plan, first verify Approved bottle demand and blower operating cases and Existing low- and high-pressure air-system data. Identify the owner and revision of every input, and keep unknown information visible until evidence closes it.
- Approved bottle demand and blower operating cases
- Existing low- and high-pressure air-system data
- Ambient, altitude, power and room conditions
- Redundancy, maintenance and production-continuity requirements
Connect This Decision to the Complete Plant
Coordinate receiver location and usable storage with headers, pressure drop, isolation, condensate, air recovery, heat rejection, power demand, ventilation, maintenance and safe inspection. Test the worst credible stop-and-restart sequence.
Responsibility Boundary for PET Bottle Blowing Compressor Sizing and Air-Receiver Plan
The buyer and packaging suppliers own approved package data and change control. The equipment resource must document the process window, utilities, interfaces and tests for the named bottle family. At the Release the High-Pressure Air Capacity Basis gate, require the supplier to document Bottle-specific air consumption and pressure envelope, while the buyer owns Ambient, altitude, power and room conditions and obtains qualified local confirmation where applicable.
- Bottle-specific air consumption and pressure envelope
- Compressor, booster, dryer, filter and receiver calculation
- Control, alarm, isolation and terminal acceptance conditions
Risks That Can Invalidate Release the High-Pressure Air Capacity Basis
A bottle that can be blown once is not yet a stable production package; material, geometry, cooling, air and downstream handling interact. In this decision, pay particular attention to Average air demand hides short peak consumption and Receiver gross volume is treated as fully usable. Record the owner, due gate, action and closure evidence for every risk.
- Average air demand hides short peak consumption
- Receiver gross volume is treated as fully usable
- Pressure passes centrally but collapses at the blower
Evidence to Close Release the High-Pressure Air Capacity Basis
Close PET Bottle Blowing Compressor Sizing and Air-Receiver Plan only when Mode-based compressed-air balance and Receiver and pressure-recovery calculation are current, reviewable, linked to the project revision, and approved by named decision owners.
- Mode-based compressed-air balance
- Receiver and pressure-recovery calculation
- Air-quality and distribution specification
- Commissioning pressure, flow and recovery trend report
Next Step: Release the High-Pressure Air Capacity Basis
Send the available inputs for PET Bottle Blowing Compressor Sizing and Air-Receiver Plan, including Approved bottle demand and blower operating cases, for a project-specific interface review. A project-specific review can organize open inputs and interfaces, but final scope, performance, responsibilities and commercial commitments exist only in the signed technical and commercial agreement.
