The BoxLayout respects the components' requested maximum sizes and also lets you align components.
For many cases flexible Layout:
- GridBagLayout
- SpringLayout
- BoxLayout

Istilah-istilah di kompresor angin
Kompresor Udara Bertekanan Rendah: di bawah 145 PSI (atau 10 bar) Kompresor Udara Bertekanan Sedang: antara 145 dan 1.160 PSI (atau 10 hingga 80 bar) Kompresor Udara Bertekanan Tinggi: antara 1.160 dan 15.000 PSI (80 dan 1.000 bar) Hyper -Kompresor Udara Bertekanan dan Sangat Tinggi: lebih dari 15.000 PSI (1.000 bar).
Pada spray gun ini jarak dan tekanan udara sangat mempengaruhi hasil dari pelapisan yang dilakukan, jarak spray yang terjadi pada umumnya adalah 152,4 mm – 300 mm serta besar tekanan udara yang baik agar spray gun dapat beratomasi dengan baik sebesar 2 - 5 bar [3].
Tekanan yang dihasilkan di dalam tangki kompresor udara diukur dalam bar dan pound per inci persegi, atau PSI. Kebanyakan kompresor memiliki tekanan kerja 8 bar atau 115 PSI, yang lebih dari cukup untuk peralatan udara DIY dan hobi (biasanya sekitar 90 PSI).
Namun sebaiknya Anda memiliki kompresor yang menghasilkan PSI lebih tinggi dari yang Anda perlukan karena tekanan udara akan turun seiring penggunaan. Aturan praktis yang baik adalah memiliki setidaknya 35% lebih banyak dari 90 PSI yang diperlukan untuk alat tersebut, atau sekitar 120 PSI . Dengan cara ini, Anda akan yakin akan tekanan yang konsisten.
1/2 HP ~ 7 BAR ~ 101.5 PSI s/d 8 BAR ~ 116 PSI
3/4 HP ~ 10 BAR ~ 145 PSI
