No. 139
Proclamation on the national standard pub li shing of Code for Des ign of Compressed Air
Station . Code for Design of Compressed A ir Station, in number of GB 50029-2003, is hereby
approved to be a national standard and executed from June 1, 2003 . Clause 3.0.6, 3.0.11, 3.0.12,
3.0.14, 4.0.7(2)(4), 4.0 .1 2, 6.0.3 , 6.0.8 and 6.0.9 are compulsory clauses and should be strictly
executed. At meanwhile, the former Code for Design of Compressed Air Station GBJ29-90 is
avoided.
China Planning Press publishes this code under the organization of Standard Norm Study
Station of Ministry of Construction.
Ministry of Construction of the People's Republic of China

Forewords
To meet the requirement from Jianbiao [ 1997] No. I 08 Writ issued by the Ministry of
Construction, the revised Code is achieved base on Code for Design of Compressed Air Station GBJ
29-90 by China Machinery lntemational Engineering Design and Research Institute (the eighth Study
Institute of former the Ministry of Machinety Industry) together with other departments.
During the revis ion, after widely investigation and shtdy, careful conclusion was made on
experience respect of design and app lication since the former Code was executed. Related domestic
and abroad infonnation were refetTed, in addition with necessmy tests. After auditing and finalizing,
the Ministty of Construction in No. 139 Proclamation publishes the Code for execution.
The code is divided into nine chapters with six attachments. Revis ion is major on. a clause on
centrifugal air compressor is added. former contents on helical-lobe compressor,
drying/purification of compressed air, environment protection, energy-saving, safety in product ion
and labor protection were revised or added.
All of the clauses in black in the code are obligatory ones and should be strictly executed.
Obligatory clauses in the code are response for explanation by the Ministry of Construction while
China Machinery Intemational Engineering Design and Research Institute in charge specific
technical contents. During future execution of the code, we will be pleased to accept careful
experience conclusion in conjunction with engineering practice. Any opinion and suggestion can
be post to China Machinery International Engineering Design and Research Institute (Address.
No.18, Shaoshanzhonglu, Changsha City; Post code. 41 0007; Fax. 073 1-555191 4) for reference

1 General
1.0.1 This code is revised for safety production, environment protection, energy saving, laboring
conditions improving, technical advancing and economic in compressed air stat ion design.
1.0.2 This code can be applied to the new-building, reconstruction or expansion of compressed
air station and pipe for both piston air compressor and helical-lobe air compressor which operate
pressure is less or equals to 1.25 MPa (gauge pressure), or centrifugal air compressor which is less
or equals to 500 m3/min (unit air displacement).
This code cannot be applied to the design for compressed air station and pipe at underground
we ll , cave and any other special locations .
1.0.3 Except E grade for compressed air station with cylinder oil-free lubricati on piston air
compressor and non-oil spraying helical-lobe air compressor, fire hazard danger class for any
other compressed air stations are all D grade.
1.0.4 Former building, equipment and pipe should be fully uti lized during design of
reconstruction and expansion of compressed air station and pipe.
1.0.5 Beside this code, any current national provision on obligatory standard should be followed
in design of compressed air station and pipe.
2 Layout of compressed air station
2.0.1 The following factors and technical-economic comparison shou ld be concerned for layout
of compressed air station inside facto ry (or ore).
1 Nearby compressed air using and loading center;
2 Reasonable in power and water supply;
3 Reserves possibility for further expansion;
4 Away from location at which explosive or corrosive gas and dust are formed , and the
place, which has the least probability to be down-wind direction annually.
5 The distance between compressed air station and location where protection against noise
and vibration is required should meet provisions in current national related standards.
2.0.2 Building orientation of compressed air station should be favorable to nature ventilation in
equipments and under less west sunshine.
2.0.3 Isolate building should be adopted for compressed air station where a piston air
compressor, centrifugal air compressor, or helical-lobe air compressor which unit air displacement
is less or equals to 20m3/minis installed.
If compressed air station is connected or inside another building, walls for isolating are
required. Layout of compressor should locate nearby exterior wall. In a multiple-story building it
should be at the bottom st...
