  Siam Pho­ton Source II (SPS-II) is the first Thai­land¿s 4th gen­er­a­tion syn­chro­tron light source. It not only pro­vides high-en­ergy and high-bright­ness syn­chro­tron ra­di­a­tion for both aca­d­e­mic and in­dus­trial re­search after its com­ple­tion, but it is also strate­gi­cally aimed to build up a stronger Thai in­dus­trial com­mu­nity dur­ing the de­sign and con­struc­tion pe­riod. Vac­uum sys­tem is one of the sys­tems ex­pected to play a key role in lev­el­ing up the local man­u­fac­tur­ing ca­pa­bil­ity of the coun­try. Most of the main com­po­nents in the sys­tem are planned to do­mes­ti­cally fab­ri­cate through tech­nol­ogy trans­fer. In­stead of NEG coat­ing tech­nol­ogy, this vac­uum sys­tem de­sign of SPS-II stor­age ring is based on the con­ven­tional tech­nol­ogy which in­volves Thai in­dus­try po­ten­tial and ex­per­tise. This paper re­views the chal­lenges and adap­ta­tion of con­ser­v­a­tive de­sign in dense DTBA mag­net lat­tice with mag­net aper­ture lim­i­ta­tion. The vac­uum cham­bers and bend­ing mag­nets have been mod­i­fied to ac­com­mo­date IR beam­lines which are in­cluded in the sec­ond phase plan. Pres­sure pro­file of the vac­uum sys­tem in stor­age ring is eval­u­ated. Then, the progress of over­all vac­uum sys­tem of SPS-II is de­scribed.
