Compressed Air Requirements for a Cosmetic Filling Line: What to Confirm Before Buying
This guide is currently available in English. The language menu opens the other language sites, not translations of this article.
A filling-line quotation may list an air-pressure requirement without giving enough information to purchase the factory air supply. For a lotion, cream or other compatible cosmetic project, ask the equipment supplier to define the requirements of the actual configuration before committing to a compressor, dryer or distribution work.
Confirm which modules need compressed air, the required pressure at their connection points, the flow demand and its reference conditions, the required air quality, and who supplies and verifies each part. Not every packaging machine needs compressed air. A pressure number alone is not a compressor-sizing instruction.
Start with the machines in your quotation
Ask for a module-by-module utility list covering the filler, closure handling, capper, labeler and any agreed options. Record both air-using and non-air-using equipment. Do not assume that a complete line has one universal air requirement.
For example, ZXSMART's published 4-, 6-, 8- and 10-head servo piston filling configurations each list an air pressure of 0.6–0.8 MPa. This matches the source product parameter table. It does not state their air consumption, define the air-using functions, or specify a complete cosmetic line's supply.
In contrast, the published chain-plate press capping configuration lists compressed air as not required. The right question is therefore “Which parts of this approved project need air?” rather than “How much air does every packaging machine need?”
A servo piston machine name also does not identify the drive of every valve or auxiliary mechanism. Ask the supplier to explain the air connections for the ordered configuration. This guide does not describe the listed servo equipment as a purely pneumatic piston filler.
Pressure and air demand answer different questions
Pressure describes the supply condition the equipment needs at an agreed point. Flow demand describes how much air is required under stated operating conditions. A supply can have a suitable pressure reading while idle without proving that it can support the planned equipment running together.
When a supplier gives a flow value, ask what the units and reference conditions mean. Keep the stated conditions with the value rather than comparing bare L/min or m³/min figures from different quotations. Also ask whether the figure is average use, a peak requirement, or a value tied to a particular speed and configuration.
Provide the intended operating pattern: which modules run together, the target sustained output, normal stops and restarts, and other factory equipment sharing the supply. The machine supplier should confirm equipment requirements; a qualified compressed-air supplier should assess the compressor, treatment, storage and distribution arrangement for the site. Do not derive capacity from the published pressure range alone.
Specify what the air is used for
Ask whether the air is used only for machine functions or may contact the container interior or product. These uses should not be treated as interchangeable. Have the responsible supplier define the applicable particle, water and oil requirements and identify where they must be achieved.
Confirm the air-treatment and maintenance responsibilities in writing. Do not assume that a filter, dryer, oil-free compressor or a particular air-quality class is included because a quotation says “clean air.” This checklist does not assign a universal filtration grade or dew point to cosmetic filling.
If the project includes bottle preparation, use the separate cosmetic bottle preparation guide to define that process. An air connection by itself is not evidence of validated cleaning, sterile production or regulatory compliance.
Ask for a written utility schedule
Keep these questions beside the machine list before approving the purchase. A blank field means a requirement still needs confirmation, not that its value is zero.
| Confirm before purchase | Ask the supplier to record |
|---|---|
| Equipment scope | Each module, its air-using functions, agreed options, and any machine that needs no compressed air. |
| Pressure at the equipment | Required operating condition, connection point and where pressure will be checked during the agreed run. |
| Air demand | Confirmed flow, units, reference conditions, operating speed and whether the figure describes average or peak demand. |
| Shared supply | Which line modules and other factory users can run simultaneously, including planned expansion. |
| Air quality | Required quality for each use, its verification point, and the supplier responsible for defining it. |
| Interfaces | Machine connection details and the agreed boundary between factory pipework, treatment equipment and machine supply. |
| Commercial responsibility | Who supplies, installs, commissions and maintains each item; clearly list exclusions. |
| Acceptance evidence | Agreed operating conditions, measurements, pass criteria, records and responsibility for resolving deviations. |
Keep these requirements with the complete project quotation. A price comparison is incomplete if one proposal includes utility work and another assumes the buyer will provide it.
Plan the check under the agreed operating conditions
Before shipment, compare the supplier's confirmed requirements with the site's available supply and identify who will resolve any gap. Agree which measurements will be taken during the planned equipment operation, including the simultaneous use that matters to the project.
Factory acceptance and site acceptance serve different purposes. A successful supplier demonstration does not prove that different factory pipework, shared air users or treatment equipment will support the installed line. Use the factory acceptance plan and installation and commissioning checklist to keep the requirements and site evidence together.
Have qualified personnel carry out any installation, measurement or adjustment under the site's safety procedure. This article is a purchasing checklist, not an instruction to increase pressure, alter a vessel or modify machine air controls.
Buyer FAQ
Does every cosmetic packaging machine need compressed air?
No. Check each approved machine configuration. ZXSMART's published chain-plate press capper lists compressed air as not required, while its listed 4-, 6-, 8- and 10-head servo piston configurations include an air-pressure requirement.
Does a pressure requirement tell me which compressor to buy?
No. Pressure alone does not specify flow demand, reference conditions, air quality, simultaneous use or the losses through the site's distribution and treatment system. Obtain the project requirements and have a qualified compressed-air supplier assess the supply.
Can I use one machine's air-consumption figure for the whole line?
No. Confirm the demand and operating conditions of every air-using module, including agreed options and simultaneous operation. A figure for another machine or configuration is not a whole-line specification.
Does a servo piston machine name explain every air-driven function?
No. The machine name does not identify the drive of every valve, actuator or auxiliary mechanism. Ask the supplier to identify the air-using functions in the approved configuration instead of assuming that every movement is pneumatic or that no air is needed.
What should I send for an initial air-requirement review?
Send the product, containers and closures, target output, proposed machine list, planned simultaneous operations and available site utility information. Ask for the missing requirements and responsibility split in writing before buying supply equipment.
Confirm the machine scope before buying the air supply
Share your cosmetic product, bottle and closure formats, required output and available factory utility information. ZXSMART can review the proposed filling, capping and labeling configuration and identify which project requirements need confirmation.

Sources and scope
- Buyer question: Reddit: Air compressor help, November 27, 2021. A business buyer asks about supply requirements for a pneumatic food filler. This is a question signal, not a cosmetic customer case, ZXSMART performance test or engineering authority. No commenter compressor-sizing recommendation is adopted here.
- General technical basis: CAGI: Working with Compressed Air, particularly equipment sizing and pressure drop. It distinguishes demand, pressure and air quality. It does not certify a ZXSMART configuration or supply a missing project value.
- Machine facts: ZXSMART's supplied product parameter table, “02_基础参数” rows 19–22, supports the listed piston configurations' pressure range. Their published consumption and complete drive allocation are not established by that table. The linked product pages identify the configurations discussed above.
