PSF-T7 - T7 promoter plasmid allows transcription of RNA using the T7 bacteriophage polymerase. If you are using an in vitro transcription kit the RNA produced from this vector will be uncapped and not poly-adenylated making it unsuitable for expression in mammalian cells however some kits are available that will add these mRNA features. The PSF-T7 - T7 promoter can also be used for inducible gene expression in cell lines that contain the T7 polymerase.

Almost all SnapFast vectors contain a T7 terminator downstream of the multiple cloning site that will enable transcription termination. If required the vector can also be digested at a restriction site that is 3 prime to the end of your gene to allow run-off of the polymerase rather than exploiting the hairpin T7 terminator. If you are expressing your gene in a Vaccinia virus-free mammalian T7 system it will require an IRES upstream of your gene because of the absence of a 5 prime cap on the RNA produced.
