About
The Legend
Behind the Booth
Where precision sewing meets inflatable engineering — a story built on precision sewing and inflatable engineering.
The Name: Sew + Inflatable
Sewinfla is a compound of two disciplines that define everything we do. Sewing — the craft of joining materials with precision, strength, and durability. Inflatable — the engineering of tensioned fabric structures that create controlled environments anywhere. Together, they form the foundation of the world's most trusted portable spray booth.
But there's another layer. Sew also means win — and that's the standard we hold ourselves to. Every stitch, every seam, every booth that leaves our facility is built to help our customers sew their own winner's flag.
Engineered, Not Assembled
Three traits that define an engineering-first brand.
Data-Driven
We don't guess. Every design decision — from stitch density to blower wattage — is validated by performance data collected from thousands of hours of real-world use across 30+ countries.
Technically Paranoid
We test until it breaks, then redesign until it doesn't. Our activated-carbon filtration system underwent 18 iterations before shipping. Our double-stitched seams are rated for 3× operational load.
Unapologetically Premium
We don't compete on price alone — we compete on engineering integrity. Every Sewinfla booth uses commercial-grade 210D Oxford fabric minimum, YKK zippers, and CE/UL-certified blowers. If it isn't specified for professional use, it doesn't ship under our name.
If You Can Sew a Spacesuit,
You Can Sew Anything
A spacesuit is the ultimate sewing challenge: a flexible, pressurized, life-sustaining environment that must survive vacuum, radiation, and extreme temperatures — all held together by seams. It's the highest expression of both sewing and inflatable technology.
Our inflatable paint booth applies the same principles: a precision-sewn, positively-pressurized environment that controls airflow, captures particulates, and withstands the rigors of professional use — day after day, job after job. That's why our logo features an astronaut: it's a daily reminder of the standard we build to.
Sew the Winner's Flag
Every painter who steps into a Sewinfla booth is chasing a standard — a perfect finish, a satisfied customer, a reputation built one job at a time. Our role is simple: give them the controlled environment to achieve it.
The booth doesn't spray the paint. The painter does. But without consistent airflow, proper filtration, and reliable containment, even the best painter fights variables they can't control. We eliminate those variables so they can focus on what matters: sewing their winner's flag.
Three Principles We Build By
① Serve Real Needs
Every feature in our booth exists because a professional painter asked for it. Exhaust fan ports? Requested by fleet managers. Reflective insulated windows? Demanded by Arizona body shops. We listen, then we engineer.
② Material Integrity
We source the same fabric mills trusted by military and outdoor equipment manufacturers. Every batch is tested for tensile strength, UV resistance, and chemical compatibility before it enters our production line.
③ Affordable Excellence
A $50,000 fixed spray booth isn't the only path to professional results. By engineering for portability without compromising filtration or durability, we deliver 90% of the capability at 10% of the cost. That's not budget — that's value creation through engineering.
Where Sewinfla Booths Are Made
American engineering. Global manufacturing. US-based stock and support.
Engineered in the USA
Product design, airflow engineering, fabric specification, and quality-control standards are developed by our team at our La Verne, California headquarters.
Manufactured in China & Vietnam
Booths are sewn and assembled on our production lines in China and Vietnam, under US-developed specifications. Every batch is inspected before it ships.
Stocked & Serviced in the USA
Finished inventory is stocked at our La Verne, California warehouse, plus warehouses in the UK and Australia. Warranty service, spare parts, and customer support are handled by our US team.
Our Promise
We Build the Environment.
You Build the Reputation.
Three granted US design patents. Customers in 60+ countries. One standard: engineered for results.

The team behind the brand
Sewinfla is the brand of an integrated manufacturer. Production runs in the group's own factories — Guangzhou TKL Industrial Co., Ltd in Guangzhou, China and TKL-VN Industrial Co., Ltd in Ho Chi Minh City, Vietnam — while North American operations, US inventory and support are handled by EJAEE INC in La Verne, California. Same ownership, same engineering team.
Both sides state the same credential: over 20 years of design and manufacturing experience in the inflatable industry. That experience is the team's and the factory's; the Sewinfla brand itself dates from 2014, and the US operation was built onshore afterwards so the factory would have an American front door.
What This Page's Claims Rest On
Five things on this page can be checked without asking us. The patents are published documents, the entities are registered companies, the fabric claims are published test methods, and the origin wording follows a federal definition we deliberately hold ourselves to rather than one we stretch.
- Three US design patents — open and readable in full. USD959699S1, USD982183S1 and USD956194S1 are granted and active. A US design patent protects the ornamental appearance of the product — the shape of the booth, not the airflow inside it — and the USPTO patent public search is the independent route to the same records.
- EJAEE INC — the US entity named in this site's footer. North American operations, US inventory, warranty service and support run through it from La Verne, California. A registered US company is checkable in its state's business registry; California's business search is the one relevant to a La Verne operation.
- Guangzhou TKL Industrial Co., Ltd and TKL-VN Industrial Co., Ltd — the production entities. Same ownership and engineering team as the US operation. Those two names are printed on the documentation that ships with a booth, so anyone holding the paperwork can match it against the entities named here.
- ASTM D751, D5034 and D2261, plus NFPA 701 — what “tested fabric” means in numbers. A coated-fabric booth wall is judged by the coated-fabric test battery — grab and cut-strip breaking strength, tear, coating-to-fabric adhesion, seam strength — and evaluated for flame propagation by NFPA 701. “Tensile strength, UV resistance and chemical compatibility” only mean something once the test behind them is named, which is why the standards are listed rather than the adjectives.
- FTC guidance on unqualified U.S. origin claims — the definition we deliberately do not claim to meet. Our booths are engineered and stocked in the United States and manufactured in China and Vietnam, so they are described as US-engineered, US-stock and never as a U.S.-origin product. The “all or virtually all” threshold in that guidance is exactly why the distinction is written out instead of being left to inference.
